[kvm-devel] kvm+virtmanager can't save machine state?
hi all, i use: fc7, built in xen, kvm. i boot my machine into normal kernal and install a guest os by vir-manager, and i encounter a strange situation the "save" command from virtual-manager menu failed! it pop out a small windows seem want to tell me something, but it quickly disappeared. what's thing happens? btw, the "save" function is ok when xen+virtmanager. regards. youhongyu 20070629- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

The window shouldn't have disappeared like that - it should have told you that this isn't supported We can't support save/restore of KVM guests in virt-manager at this time. QEMU 0.9.0 was really very unhelpful and removed the ability specify a filename for saving VM state, assuming that everyone happens to be using a qcow file :-( Not much use if you are using raw files, or physical volumes, or LVM which are the primary storage types used in virt-manager currently.

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 also works for "live" savevm/loadvm (kids don't try
this at home).
Hope that helps,
Uri.

One of these days, I plan on implementing a checkpoint:// protocol that
always "fails" and does a live savevm to disk without shutting down the VM.
