Hi
I am running kvm-78 with libvirt 0.6.1 and see the following error from time to time when my linux-ha cluster tries to run "virsh domstate" to figure out a virtual machine's state:
error: failed to connect to the hypervisor
In syslog, I see:
libvirtd: 23:39:11.357: error : Failed to set close-on-exec file descriptor flag
Due to this error, the cluster assumes the machine is not running okay and reboots it in order to fix things.
This happened twice in 2 months with 10 machines being queried like that each minute (read: not too well reproducable)
What is this and how could I work around it or is this fixed in newer versions and so worth an upgrade?
I've never seen that error message before, but if I had to guess I'd say that was a bug in 0.6.1 libvirt. There were quite a few really nasty bugs in that release, which cause really wierd, random, and inexplicable problems, so I'd really recommend updating to at least 0.6.3 if at all possible.
