[libvirt-users] Libvirt-LXC bug/error
Hi all, I am trying to run LXC containers with the libvirt utils. I encountered many difficulties but solved all of them, except a last one... This is why I need your help. My problem is simple, here is the log of the command: http://pastebin.com/2zrjYLiT When I try to do: virsh --connect lxc:/// start instance-00000010 I have the errors: 2012-01-16 10:46:47.739+0000: 1: error : lxcContainerMountDevFS:518 : Failed to mount /dev/pts in container: No such file or directory And others (see the trace on pastebin). Does anybody have an idea about how to deal with this problem? Thanks for your answers. Best regards. Sam
Hi, I tried to create a fresh container with a minimal configuration : Here is the configuration: http://paste.debian.net/152553/ I built a minimal rootfs with busybox as descriped in: http://berrange.com/posts/2011/09/27/getting-started-with-lxc-using-libvirt/ And I also have the same problem: root@PAR-SRV-01-002:/etc# virsh --connect lxc:/// start simple error: Failed to start domain simple error: internal error guest failed to start: 2012-01-17 11:20:35.212+0000: 13808: info : libvirt version: 0.9.8 2012-01-17 11:20:35.212+0000: 13808: warning : lxcCapsInit:77 : Failed to get host power management capabilities PATH=/bin:/sbin TERM=linux LIBVIRT_LXC_UUID=3d477435-fd58-11a4-2d4e-49092034871e LIBVIRT_LXC_NAME=simple /init 2012-01-17 11:20:35.229+0000: 1: info : libvirt version: 0.9.8 2012-01-17 11:20:35.229+0000: 1: error : lxcContainerMountDevFS:518 : Failed to mount /dev/pts in container: No such file or directory 2012-01-17 11:20:35.229+0000: 13809: info : libvirt version: 0.9.8 2012-01-17 11:20:35.229+0000: 13809: error : lxcControllerRun:1445 : error receiving signal from container: Input/output error After many reseach, I finally open a bug: https://bugzilla.redhat.com/show_bug.cgi?id=782038 Tell me if you need more informations.

And I also have the same problem:

For the benefit of the mailing list archives, this turned to be caused by the filesystem path containing a component that was an absolute symbolic link. Debian's LXC package likes to create directories like this for containers by default, so it is surprising we've not seen it before.
