[kvm-devel] Automatically hibernate XP guest on suspend?

[David A. <da...@bo...>]

If I suspend my host while running a Windows XP guest, the whole machine
crashes, so I was hoping to automate hibernation of the guest OS and
integrate that into my host's suspend process.  Does anyone know how to
do that?

TIA,

Hi Dave,

What host OS are you running?

It's certainly new enough to support suspend/resume with running VMs.  
What kernel does it have?

Do not meddle in the internals of kernels, for they are subtle and quick to panic.

It's doable (not sure how), but kvm ought not to crash when resuming.

Surely.  Of course I would prefer for that bug to be fixed ;-)

If I run the same disk image using virt-manager I can suspend it quickly
through the virt-manager interface (or virsh), and suspend/resume works.
However, I don't know how to replicate the networking I get from

  kvm -no-acpi -smp 1 -m 1000 -redir tcp:3389::3389 -usb -usbdevice tablet -boot c /mnt/usr_local/vm/xp-overlay.qcow2 

which is my usual launch command.  In particular, I don't know how to
reproduce the -redir tcp:3389::3389 in that VM file, and the guest seems
to think it's running on different hardware.  If I could figure out how
to get the equivalent of virsh's suspend command when invoking kvm from
the command line, or how to get virtual-manager to run my existing VM
as-is, I'd be all set.  Knowing both would be best of all ;-)

Any hints?
