Re: [libvirt] [PATCH v3] implement virsh dump for qemu guests

This patch uses a stop/migrate/cont combination to implement "virsh dump" for QEMU guests (BZ507551). The code is mostly based on qemudDomainSave, except that the XML prolog is not included as it is not needed to examine the dump with e.g. crash. The plan is to implement live dumping in the future. When that is done, it shouldn't require reindentation. This plan is also the reason for the "weird" resume = (vm->state == VIR_DOMAIN_RUNNING); if (vm->state == VIR_DOMAIN_RUNNING) { ... } * src/qemu_driver.c (qemudDomainCoreDump): New. (qemuDriver): Add core dump function. --- The virsh dump for xen does not crash the VM, and so does this KVM implementation.
