Greetings all,
I've set up a new oVirt installation and it's behaving strangely with regard to
virtual machine image files on the NFS storage. Whenever I shut down a machine it's
changing the owner of the image to root:root (0:0) instead of vdsm:kvm (36:36). After
that it can't start or do anything with that image again until I manually change the
ownership back. Everything works fine again until I shut the machine down. I assume this
is some mistake I've made in installation. I did not have this problem in the test
environment, but I'm stumped as to what went wrong.

Eduardo\Federico, any thoughts ? udev configuration maybe?

Hi Jacob,
could you check the dynamic_ownership in /etc/libvirt/qemu.conf:
# grep dynamic_ownership /etc/libvirt/qemu.conf
#dynamic_ownership = 1
dynamic_ownership=0 # by vdsm
Thanks,

Frederico,
Thank you for responding. I checked the qemu.conf file on all of the nodes and it was
correct. What's even more strange is that last night I put all of the nodes into
maintenance mode and restarted them. No particular reason for this but I was trying
anything I could think of. Now the ownership remains correct. I suppose I'll never
know what I did wrong, but at least it is working.
I found only 2 other anomalies. One, the live migration did not work because TLS was
disabled on the nodes. The "listen_tls = 0" flag was set in
/etc/libvirt/libvirtd.conf. I commented that out and migration works.
The second thing I noticed is that the iptables service is not starting. This doesn't
hinder functionality, but it's a security issue. I'm still checking into why.
I doubt either of these issues caused my ownership problem. I'm sure it's some
mistake I made. Hopefully I won't make it again next time.
Thank you again,
-Jacob
