I use NFS for having the guests mount separate directories on the host,
then I rsync to these from the UMLs. Works for me, and is easily cron:able
from inside the UMLs. This was convenient since my host have a directory
with shared resources for the UMLs anyway, so NFS was already set up.

How about attaching a disk with mconsole, mount it in the guest, copy
the data, umount, detach disk. done?

I'm not sure about it but that bug could be one of the possible causes.

depends how consistent a backup you need and what level of
resource usage you can tolerate. e.g.
I'm not sure I follow, but I'll take your word for it. Is it your
opinion, then, that if I upgrade to 2.6.19.2 it will fix my problem?

Hmm... What is the preferred method of backup for a VM then? As I
said, I'd rather not install ssh on every guest if I don't have to.

It seems to be nearly instant, yes. If not instant, it is within 2-3
minutes. I am using ext3, so I should be mounting read-only. I wasn't,
but somehow it doesn't seem like messing with the journal a little bit
would screw up the system in this manner... I'll fix the read-only part
and keep the

Between stop and go the filesystem is still mounted on the guest right?
If so, you are screwing the filesystems by mounting them on the host:
the mount command will run fixups on the (journaled?) filesystem.
(You could try mounting read-only - but still, bad idea IMO)

I just discovered a bug in UML. Under a vanilla edgy eft Ubuntu install
as the host (with the linux-generic package installed for the kernel),
and using linux2.6.16.29-bs2-32bit (from Blaisorblade) for the guest
kernel, using the uml_mconsole HANDLE stop command can freeze the guest
