Subject: libvirt-bin: autostart fails on reboot
Package: libvirt-bin
Version: 0.8.3-1
Severity: normal
*** Please type your report below this line ***
I have a routed setup of kvm (with libvirt).
My tun devices are created in /etc/network/interfaces.
auto tap0
iface tap0 inet static
address xxx.xxx.xxx.xxx
netmask 255.255.255.255
tunctl_user libvirt-qemu
up route add xxx.xxx.xxx.xxx/32 dev tap0
But when I reboot my host server, and libvirt starts, it can't start the
guests.
I get the following error:
Sep 21 21:28:51 cloud libvirtd: 21:28:51.046: error :
qemudReadLogOutput:2118 : internal error Process exited while reading
console log output: char device redirected to /dev/pts/1#012could not
open /dev/net/tun: Permission denied#012
Sep 21 21:28:51 cloud libvirtd: 21:28:51.047: error :
qemuAutostartDomain:827 : Failed to autostart VM 'dupondje': internal
error Process exited while reading console log output: char device
redirected to /dev/pts/1#012could not open /dev/net/tun: Permission
denied#012
It seems to fail because the tap0 doesn't exist yet, and libvirt tries
to make it.
If I restart libvirt-bin after like 30 seconds, the devices get started
without any issue.
So it seems like there is some race condition, that makes libvirt-bin
start before the network is initialized.
