vzdump no longer "sees" KVM VM's

[jcpham]

I've run into a problem where vzdump no longer recognizes or "sees" the two KVM virtual machines on my PVE host. Several other things are also concerning me. I'll post the all of the output and see if anyone here can help me or decipher what is going on. vzdump stopped functioning after apt-get dist-upgrade.

Before you start asking. Yes, we do also have webmin and Dell Openmanage installed on the PVE host.
That is the current, active sources.list for apt, however.

dist-upgrade is what seems to have started this problem. I stopped my VM's, did the dist-upgrade, rebooted, and ever since then vzdump does not see the KVM VM's.

This host started as 0.9 or 1.0 and has been upgraded a few times to the current version. I'm concerned about my current kernel version and the output versions of pveversion -v.

I was expecting to be on 1.4/4390 after dist-upgrade, but I'm not and I'm not sure why.

I also need to point out that someone else seems to be having the same problem as me with vzdump.

My host is also a single node, but I do not have any OpenVZ VM's, just the two KVM VM's:

Please can you post the content of /etc/cron.d/vzdump

And what is the output of

This is much too old - are there any errors when you try to update?

# apt-get update
# apt-get dist-upgrade

Please can you post the output of those commands?

 

[jcpham]

I think my sources.list was way out of date. Just did a dist-upgrade and it looks to have upgraded correctly. Rebooting server now. Will test vzdump shortly.

Resolved: vzdump no longer "sees" KVM VM's

Problem resolved. /etc/apt/sources.list was incorrect and out of date. I checked another PVE host and updated my repos:

deb http://ftp.us.debian.org/debian lenny main contrib

# PVE packages provided by proxmox.com
deb http://download.proxmox.com/debian lenny pve

# security updates
deb http://security.debian.org/ lenny/updates main contrib

apt-get update
apt-get dist-upgrade

And everything updated successfully. vzdump works again now.

 

[jcpham]

sorry for the double post. not sure how I did that.

vzdump works again now.
