So came into the office this morning, found out that
/var/lib/libvirtd/qemu/saves was symlinked and the contents deleted. Now
I'm experiencing all sorts of flakiness aside from the fact that the
machine save states are GONE! I have the original .img files for the
virtual hosts is there a way to salvage this given what has happened or is
this developer SOL?

Here is the output of /var/log/messages during a libvirtd restart

What, no backups on his directories?

This is bad, and you need to find out why it's happening. Did that error
ever show up before? If not, what changed or added a rule that's broken?

Well virt-manager is acting funny.. not sure if it has anything to do with
the iptables error or more-so to the dbus_bus_get failed error. I can't
even create new VMs from scratch.

So, it looks like installed a new kernel. so whats' the correlation between
the kernel libvirtd is originally installed with and a new one...

Weird. What's the symlink point to? Might someone have moved the save
states to another partition, something I'm considering doing on our VM
servers?

If the symlink is bogus, have you tried removing it and making an empty
"save" dir again? Mine here is empty, publicly readable and owned by
qemu:qemu:

[qemu/save]#root@gammak11*> ls -la /var/lib/libvirt/qemu/save
total 0K
drwxr-xr-x. 2 qemu qemu 6 Sep 6 22:48 .
drwxr-x---. 5 qemu qemu 94 Jan 3 17:29 ..

so there's no funny internal structure to worry about.

What sort of flakiness? I would guess that there is more damage than
just this missing directory.

I'd have thought having the .img files is enough. Make a new VM using
those .img files. MAKE SURE you don't reinitialise the disc images!
Probably a good idea to back them up by hand first, example:

rsync -aSP foo.img /path/to/backups/foo.img

The "S" is important, to copy sparse files.

I'll let Mr Roth address these; out of my expertise, but it looks like
the per-VM rules are already scrubbed. This may get fixed during
libvirtd startup. Does it repeat if you do another stop-then-start?

Is dbus running?

No idea here, myself.

But I'm pretty sure more than your save state symlink is damaged.
