| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On 09/04/2012 08:20 AM, Eric Blake wrote: > tv_sec is required by POSIX to be > of type time_t; so this is a bug in the OpenBSD header > [for declaring it as long] Most likely this problem arose because of the patch I pushed in gnulib commit e07d7c40f3ca5ec410cf5aa6fa03cfe51e712039. Previously, gnulib required timeval's tv_sec to be the same size as time_t. But now, it requires only that tv_sec be big enough to hold a time_t. This patch was needed for Emacs. Without the patch, gnulib replaced struct timeval on OpenBSD, and this messed up utimens.c, and Emacs wouldn't build. Alternatively, gnulib could substitute its own struct timeval for the system's, wrapping every struct timeval-using function (gettimeofday, futimesat, futimes, lutimes, etc. That'd be more work, though. And it would introduce some performance issues with gettimeofday, which is supposed to be fast. I've been trying to get away from using struct timeval, and to use the higher-resolution struct timespec instead, so messing with these obsolescent interfaces has been lower priority for me. But if someone wants to take the more-ambitious approach that'd be fine, I expect. For this particular case, though, how about if we avoid the problem entirely? libvirt doesn't need to use struct timeval here at all. It makes libvirt smaller and probably faster, and it ports to OpenBSD without messing with gnulib.

* Fix issue of PF brought down if VF is 8021.Qbh and pci passthroughNishank Trivedi2012-08-301-0/+1
| | | | | | | | | | | | | | | | If a 8021.Qbh network device supports SRIOV and its VF is being used in pci passthrough mode, when the guest is shutdown or destroyed, the PF inteface is also brought down. qemuDomainHostdevNetConfigRestore() finds out the PF for provided hostdev (which is VF) and passes it to virNetDevPortProfileDisassociate() as linkdev. Later, linkdev gets passed to virNetDevSetOnline() where the interface is brought down by clearing IFF_UP flag. Bringing down a PF, when only VF is being brought down is not expected behavior. This patch adds a check so that virNetDevSetOnline() is called only for PF and not if device is a VF. Signed-off-by: Nishank Trivedi <nistrive@cisco.com>
* dnsmasq: avoid forwarding queries without a domainGene Czarcinski2012-08-221-0/+1
| | | | | | | | | | dnsmasq is forwarding a number of queries upstream that should not be done. There still remains an MX query for a plain name with no domain specified that will be forwarded is dnsmasq has --domain=xxx --local=/xxx/ specified. This does not happen with no domain name and --local=// ... not a libvirt problem. BTW, thanks again to Claudio Bley!

* network: use firewalld instead of iptables, when availableThomas Woerner2012-08-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * configure.ac, spec file: firewalld defaults to enabled if dbus is available, otherwise is disabled. If --with_firewalld is explicitly requested and dbus is not available, configure will fail. * bridge_driver: add dbus filters to get the FirewallD1.Reloaded signal and DBus.NameOwnerChanged on org.fedoraproject.FirewallD1. When these are encountered, reload all the iptables reuls of all libvirt's virtual networks (similar to what happens when libvirtd is restarted). * iptables, ebtables: use firewall-cmd's direct passthrough interface when available, otherwise use iptables and ebtables commands. This decision is made once the first time libvirt calls iptables/ebtables, and that decision is maintained for the life of libvirtd. * Note that the nwfilter part of this patch was separated out into another patch by Stefan in V2, so that needs to be revised and re-reviewed as well. ================ All the configure.ac and specfile changes are unchanged from Thomas' V3. V3 re-ran "firewall-cmd --state" every time a new rule was added, which was extremely inefficient. V4 uses VIR_ONCE_GLOBAL_INIT to set up a one-time initialization function. The VIR_ONCE_GLOBAL_INIT(x) macro references a static function called vir(Ip|Eb)OnceInit(), which will then be called the first time that the static function vir(Ip|Eb)TablesInitialize() is called (that function is defined for you by the macro). This is thread-safe, so there is no chance of any race. IMPORTANT NOTE: I've left the VIR_DEBUG messages in these two init functions (one for iptables, on for ebtables) as VIR_WARN so that I don't have to turn on all the other debug message just to see these. Even if this patch doesn't need any other modification, those messages need to be changed to VIR_DEBUG before pushing. This one-time initialization works well. However, I've encountered problems with testing: 1) Whenever I have enabled the firewalld service, *all* attempts to call firewall-cmd from within libvirtd end with firewall-cmd hanging internally somewhere. This is *not* the case if firewall-cmd returns non-0 in response to "firewall-cmd --state" (i.e. *that* command runs and returns to libvirt successfully.) 2) If I start libvirtd while firewalld is stopped, then start firewalld later, this triggers libvirtd to reload its iptables rules, however it also spits out a *ton* of complaints about deletion failing (I suppose because firewalld has nuked all of libvirt's rules). I guess we need to suppress those messages (which is a more annoying problem to fix than you might think, but that's another story). 3) I noticed a few times during this long line of errors that firewalld made a complaint about "Resource Temporarily unavailable. Having libvirtd access iptables commands directly at the same time as firewalld is doing so is apparently problematic. 4) In general, I'm concerned about the "set it once and never change it" method - if firewalld is disabled at libvirtd startup, causing libvirtd to always use iptables/ebtables directly, this won't cause *terrible* problems, but if libvirtd decides to use firewall-cmd and firewalld is later disabled, libvirtd will not be able to recover.

* Add a sheepdog backend for the storage driverSebastian Wiedenroth2012-07-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch brings support to manage sheepdog pools and volumes to libvirt. It uses the "collie" command-line utility that comes with sheepdog for that. A sheepdog pool in libvirt maps to a sheepdog cluster. It needs a host and port to connect to, which in most cases is just going to be the default of localhost on port 7000. A sheepdog volume in libvirt maps to a sheepdog vdi. To create one specify the pool, a name and the capacity. Volumes can also be resized later. In the volume XML the vdi name has to be put into the <target><path>. To use the volume as a disk source for virtual machines specify the vdi name as "name" attribute of the <source>. The host and port information from the pool are specified inside the host tag. <disk type='network'> ... <source protocol="sheepdog" name="vdi_name"> <host name="localhost" port="7000"/> </source> </disk> To work right this patch parses the output of collie, so it relies on the raw output option. There recently was a bug which caused size information to be reported wrong. This is fixed upstream already and will be in the next release. Signed-off-by: Sebastian Wiedenroth <wiedi@frubar.net>

* Fix vm's outbound traffic control problemEiichi Tsukata2012-06-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hello, This is a patch to fix vm's outbound traffic control problem. Currently, vm's outbound traffic control by libvirt doesn't go well. This problem was previously discussed at libvir-list ML, however it seems that there isn't still any answer to the problem. http://www.redhat.com/archives/libvir-list/2011-August/msg00333.html I measured Guest(with virtio-net) to Host TCP throughput with the command "netperf -H". Here are the outbound QoS parameters and the results. outbound average rate[kilobytes/s] : Guest to Host throughput[Mbit/s] ====================================================================== 1024 (8Mbit/s) : 4.56 2048 (16Mbit/s) : 3.29 4096 (32Mbit/s) : 3.35 8192 (64Mbit/s) : 3.95 16384 (128Mbit/s) : 4.08 32768 (256Mbit/s) : 3.94 65536 (512Mbit/s) : 3.23 The outbound traffic goes down unreasonably and is even not controled. The cause of this problem is too large mtu value in "tc filter" command run by libvirt. The command uses burst value to set mtu and the burst is equal to average rate value if it's not set. This value is too large. For example if the average rate is set to 1024 kilobytes/s, the mtu value is set to 1024 kilobytes. That's too large compared to the size of network packets. Here libvirt applies tc ingress filter to Host's vnet(tun) device. Tc ingress filter is implemented with TBF(Token Buckets Filter) algorithm. TBF uses mtu value to calculate the amount of token consumed by each packet. With too large mtu value, the token consumption rate is set too large. This leads to token starvation and deterioration of TCP throughput. Then, should we use the default mtu value 2 kilobytes? The anser is No, because Guest with virtio-net device uses 65536 bytes as mtu to transmit packets to Host, and the tc filter with the default mtu value 2k drops packets whose size is larger than 2k. So, the most packets is droped and again leads to deterioration of TCP throughput. The appropriate mtu value is 65536 bytes which is equal to the maximum value of network interface device defined in <linux/netdevice.h>. The value is not so large that it causes token starvation and not so small that it drops most packets. Therefore this patch set the mtu value to 64kb(== 65535 bytes). Again, here are the outbound QoS parameters and the TCP throughput with the libvirt patched. outbound average rate[kilobytes/s] : Guest to Host throughput[Mbit/s] ====================================================================== 1024 (8Mbit/s) : 8.22 2048 (16Mbit/s) : 16.42 4096 (32Mbit/s) : 32.93 8192 (64Mbit/s) : 66.85 16384 (128Mbit/s) : 133.88 32768 (256Mbit/s) : 271.01 65536 (512Mbit/s) : 547.32 The outbound traffic conforms to the given limit.

* Fix for parallel port passthrough for QEMUBeat Jörg2012-06-041-0/+1
| | | | | | | | | | | | | | | | | | | | | I came across a bug that the command line generated for passthrough of the host parallel port /dev/parport0 by libvirt for QEMU is incorrect. It currently produces: -chardev tty,id=charparallel0,path=/dev/parport0 -device isa-parallel,chardev=charparallel0,id=parallel0 The first parameter is "tty". It sould be "parport". If I launch qemu with -chardev parport,... it works as expected. I have already filled a bug report ( https://bugzilla.redhat.com/show_bug.cgi?id=823879 ), the topic was already on the list some months ago: https://www.redhat.com/archives/libvirt-users/2011-September/msg00095.html Signed-off-by: Eric Blake <eblake@redhat.com>

| | | | | | | | | | Currently, monitoring QEMU virtual machines with standard Unix sysadmin tools is harder than it has to be. The QEMU command line is often miles long and mostly redundant, it's hard to tell which process is which.
