 Subject: [Users] image ownership
 
 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.

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,

Re: [Users] image ownership

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
