Re: [Fedora-xen] Why I can't save and restore domU.

[전상일]

Thank you for your concern.

My system is Para-virtualization.
I successed save/restore and migrate the virtual machine of gui.
But, the domU is not fedora core 6 but fedora 7(rc2).
Someone said me that fedora core 6 is support old framebuffer. 
So, He guess that this situation appeared.
I think that fedora 7 is support framebuffer more perfectly.
In fack, I'm not fix setting files at the success case.

Okay.

Do you mean that migration worked, but the framebuffer didn't come up
correctly?

Again: what does migration write to your dom0's /var/log/xen/?

If it's broken in FC-6, it needs fixing.

Err, you lost me there.

Migration and save/restore worked.

Your logs show more than just the save/restore, which makes it a bit
difficult to find the relevant bits.  I believe you saved domid 3, and
it became domid 4 on restore.

Output of xenstore-ls before save and after restore?

Any xen-vncfb processes running before save and after restore?
