With libvirt-1.0.1 I can no longer start LXC VMs from virt-manager. This applies to both pre-existing ones that worked with (I think) 1.0.0 and newly created (with the wizard) VMs. Reproducible: Always Steps to Reproduce: 1. emerge =libvirt-1.0.1 virt-manager ; /etc/init.d/libvirt restart 2. Extract a gentoo stage-3 somewhere, and put rc_sys="" in etc/rc.conf . 3. Start virt-manager, start the (system) LXC connection. 4. Follow the wizard for creating a new OS level LXC VM, selecting the folder you extracted the stage-3 to, and otherwise the defaults (NAT network, mostly). 5. Hit Finish button in wizard to boot the LXC VM. Actual Results: An error message with the following is presented: Unable to complete install: 'internal error guest failed to start: PATH=/bin:/sbin TERM=linux container=lxc-libvirt container_uuid=@@UUID-1@@ LIBVIRT_LXC_UUID=@@UUID-1@@ LIBVIRT_LXC_NAME=lxctest /sbin/init 2013-01-12 22:55:33.519+0000: 1: info : libvirt version: 1.0.1 2013-01-12 22:55:33.519+0000: 1: error : lxcContainerMountProcFuse:615 : Failed to mount /.oldroot//var/run/libvirt/lxc/lxctest/meminfo on /proc/meminfo: No such file or directory 2013-01-12 22:55:33.519+0000: 112320: info : libvirt version: 1.0.1 2013-01-12 22:55:33.519+0000: 112320: error : virLXCControllerRun:1451 : Unable to send container continue message: Broken pipe 2013-01-12 22:55:33.533+0000: 112320: error : virCommandWait:2287 : internal error Child process (ip link del veth1) unexpected exit status 1: Cannot find device "veth1" ' >Details Unable to complete install: 'internal error guest failed to start: PATH=/bin:/sbin TERM=linux container=lxc-libvirt container_uuid=@@UUID-1@@ LIBVIRT_LXC_UUID=@@UUID-1@@ LIBVIRT_LXC_NAME=lxctest /sbin/init 2013-01-12 22:55:33.519+0000: 1: info : libvirt version: 1.0.1 2013-01-12 22:55:33.519+0000: 1: error : lxcContainerMountProcFuse:615 : Failed to mount /.oldroot//var/run/libvirt/lxc/lxctest/meminfo on /proc/meminfo: No such file or directory 2013-01-12 22:55:33.519+0000: 112320: info : libvirt version: 1.0.1 2013-01-12 22:55:33.519+0000: 112320: error : virLXCControllerRun:1451 : Unable to send container continue message: Broken pipe 2013-01-12 22:55:33.533+0000: 112320: error : virCommandWait:2287 : internal error Child process (ip link del veth1) unexpected exit status 1: Cannot find device "veth1" ' Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 96, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/create.py", line 1943, in do_install guest.start_install(False, meter=meter) File "/usr/lib64/python2.7/site-packages/virtinst/Guest.py", line 1249, in start_install noboot) File "/usr/lib64/python2.7/site-packages/virtinst/Guest.py", line 1317, in _create_guest dom = self.conn.createLinux(start_xml or final_xml, 0) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 2610, in createLinux self._o = None libvirtError: internal error guest failed to start: PATH=/bin:/sbin TERM=linux container=lxc-libvirt container_uuid=@@UUID-1@@ LIBVIRT_LXC_UUID=@@UUID-1@@ LIBVIRT_LXC_NAME=lxctest /sbin/init 2013-01-12 22:55:33.519+0000: 1: info : libvirt version: 1.0.1 2013-01-12 22:55:33.519+0000: 1: error : lxcContainerMountProcFuse:615 : Failed to mount /.oldroot//var/run/libvirt/lxc/lxctest/meminfo on /proc/meminfo: No such file or directory 2013-01-12 22:55:33.519+0000: 112320: info : libvirt version: 1.0.1 2013-01-12 22:55:33.519+0000: 112320: error : virLXCControllerRun:1451 : Unable to send container continue message: Broken pipe 2013-01-12 22:55:33.533+0000: 112320: error : virCommandWait:2287 : internal error Child process (ip link del veth1) unexpected exit status 1: Cannot find device "veth1" (@@UUID-1@@ is the same UUID each time.) Expected Results: VM should have booted. AFAICT this works as expected with both libvirt-0.10.2.1 and 1.0.0. The same problem appears with Application LXCs. I'm not familiar with the virsh commands or other methods of interacting with libvirt without virt-manager, so I haven't tried that, but if someone thinks that would be helpful, I can certainly follow instructions if provided/linked. $ emerge --info libvirt virt-manager Portage 2.2.0_alpha150 (default/linux/amd64/10.0, gcc-4.6.3, glibc-2.16.0, 3.7.1-gentoofalcon1 x86_64)

A git bisect indicates df33ecdd as the commit introducing this issue. commit df33ecdd9e897cf6af56e2120d44bfbcccc80a32 Author: Gao feng <gaofeng@cn.fujitsu.com> Date: Mon Nov 12 15:02:28 2012 +0800 mount fuse's meminfo file to container's /proc/meminfo we already have virtualize meminfo for container through fuse filesystem, add function lxcContainerMountProcFuse to mount this meminfo file to the container's /proc/meminfo. So we can isolate container's /proc/meminfo from host now. Signed-off-by: Gao feng <gaofeng@cn.fujitsu.com>
Created attachment 335540 [details, diff] Patch to functionally revert df33ecdd Commit df33ecdd can't be reverted trivially due to later changes, so here's a patch removing the calls to the function introduced. This let's me boot my VMs without creating other visible complaints, but I don't make any claim to understanding the exact purpose of the removed function calls or why they cause a problem.
Created attachment 335550 [details, diff] Patch to functionally revert df33ecdd -r1 Oops, previous patch a) fails to build and b) is against latest git revision. This one works as advertised with libvirt-1.0.1 from portage.
Try the referenced patch. The easiest way to do this would be to do: $ mkdir -p /etc/portage/patches/app-emulation/libvirt-1.0.1 $ wget -O /etc/portage/patches/app-emulation/libvirt-1.0.1/0001-lxc-fix.patch "http://libvirt.org/git/?p=libvirt.git;a=patch;h=ae9874e471fc61d9d654247c2fd24d9baa455afa" $ emerge -1 libvirt $ /etc/init.d/libvirtd reload Please report back if this fixes your issue.
Hi, sorry about the delay. I have now tried the patch you suggested against libvirt-1.0.1, and found it does not solve the issue. It changes the traceback in the error message somewhat, thus I will attach it. I have also tested app-emulation/libvirt-1.0.2-r1 without any local patches applied. After the update a) All my configured VMs disappeared. A nuisance, but nontheless. They returned with a downgrade. b) Trying to start a (necessarily newly created) LXC fails with a (subtly) different error message from before, I will attach that too. I'm reopening the bug, feel free to yell at me if that's not what I'm supposed to do.
Created attachment 338022 [details] Error message, libvirt-1.0.1 with suggested patch
Created attachment 338024 [details] Error message, libvirt-1.0.2-r1 with no local patches
Created attachment 338026 [details] Error message, libvirt-1.0.2-r1 with no local patches v.2 Easierly diffable to earlier logs.
Coincidentally found this bug. As we are at libvirt 1.0.4 now for ~amd64, is the bug still alive in this version?
(I haven't followed new releases for a while, but used the attached patch with 1.0.1) This problem appears to have gone away in libvirt-1.0.4 (or possibly earlier). Application LXCs seem to work fine, and OS LXCs give me a new and very different error message. Interesting times. Closing as fixed.
Disregard that, I can't type paths correctly. The same error seems to still be printed in a slightly modified format, with libvirt-1.0.4 and current -9999. Now application LXCs work, though, at least the trivial one I accidentally made. Toggling the fuse use-flag does not affect this. Don't mind me putting this https://www.redhat.com/archives/libvirt-users/2013-February/msg00028.html here so I won't lose it.
Give it another whirl with 1.0.6. I've finally got this working for me with that.
Thank you very much! With libvirt-1.0.6 booting LXCs seems to Just Work again. :-D I have only done cursory testing, but any other issues should go in other bugs, I guess.
