Without this patch when '-no-acpi' is added to the command line and the
user issues a 'system_powerdown' qemu monitor command, we get a segmentation

Thanks for reporting the problem.
You do not need to "make -C kernel sync" with kvm-tarballs.

Actually, although not intended (and was not tested), KVM's migration
capability enables save/restore of non-qcow images.
I used it to debug the migration code.
Please look at the bottom of http://kvm.qumranet.com/kvmwiki/Migration
("savevm/loadvm to an external state file").
BTW, my little trick
I've never encountered that problem.
I haven't used "exec" migration protocol too many times though.
I have not used libvirt too many times either.
I'll look into it too.

Thanks for the patches.
There is still the mystery of different file sizes for different
migration-exec commands, all files are "valid saved image".
It seems to me that some unmodified pages are being marked as dirty, and
are being saved twice (and later loaded twice).
I'm still chasing that.

Hi Vineet,
What guest OS are you trying to run ?
Do you see anything meaningful in the system log (or dmesg) ?
What happens if you run it with '-no-kvm' ?
Sometimes exception 13 means "something is wrong with your guest image".
Try running a different guest image.

Hi Jon,
It seems KVM's savevm/loadvm has been broken since the upgrade to version 0.9.0
of QEMU.
Please apply the attached patch and retry.
Currently, saved images (aka snapshots) of QEMU are not compatible with those
of KVM, and vice versa.
In other words if you savevm a VM started with '-no-k
Hi,
Do you use a software bridge and a tun/tap device ?
If you do, what is your network configuration (host + guest) ?
If you do not, search the list to find how to do it.
You'll need to setup a bridge (either manually or using an init script posted),
and add a '-net tap,script=/etc/kvm/qemu-ifup'
When using rtc to keep qemu/host time, which is the default, qemu gets
periodically SIGIO signals.

You are correct. The disk image(s) must be available to both the sending and
