I concur with John. Check the messages log and dmesg. Something bigger
is happening. I changed /dev/null on a virtual machine to the state
that you had it in and yes, weird things happened, but as soon as I
rebooted it, it changed back to exactly what it was before (as I would
expect).
This may also explain your connectivity problem.

Can you see the virtual machine register on your VSwitch (Q LAN
DETAILS)? Can you ping it?

I've got a strange problem with a Linux guest. The only indicator we've
come up with so far is that /dev/null had it's file permissions changed
on
Friday afternoon to -rw-r--r-- 1 root root 81 2008-01-11 15:03 /dev/null
(we don't know how this was changed). One of our admins changed it back
to
666, but it was still missing the character file attributes. Everything
still worked fine, until it was rebooted on Sunday evening. Now, it
comes
up under VM, but the connections that allow us to putty to it aren't
working. It's only mounting / and when I sign on as root and try to
change
null to a character file, it tells me the file system is read-only
although
the permissions for /dev are drwxr-xr-x. It's also not mounting /opt
which
is what is on /dev/system/lvm1.
doing the mount command, we see this output.
proc on /proc type proc (rw)
(none):/ # mount -a
mount -a
mount: devpts already mounted or /dev/pts busy
mount: /dev/system/lvm1 is not a valid block device
We're in the process of trying to restore back to the last good full
volume
backup, but I'm really curious if changing /dev/null could have this
strong
of a impact and if there's any ideas of what we might be able to do to
fix
the problem without restoring.
