Re: [Libvir] [PATCH 0/7] QEMU/KVM save/restore support, take 3

Here's take 3 of the QEMU/KVM save/restore support. Thanks for your input. Changes since last time: - Remove escape sequence filtering, it's not necessary. - Clean up stdin handling in virExec, use -1 to signify unused - Add signal-safe read/write wrappers that handle EINTR and use them. - Add version and padding to image header, and check version on restore. - Include null-termination in XML data & length - Show name of conflicting domain in error message Everything seems to work well in my tests. I've run into a few rare cases where the migration doesn't work correctly (causing segfaults in the guest, or kvm to crash), but it's not libvirt's fault, and libvirt handles the failures well.
