Hi. I am using openstack, ceph and libvirt now. The live volume migration will call the libvirt rebase function in openstack nova project. https://github.com/openstack/nova/blob/stable/rocky/nova/virt/libvirt/driver.py#L1497 https://github.com/openstack/nova/blob/stable/rocky/nova/virt/libvirt/guest.py#L802 But I use the ceph as the openstack block backend. And the type of

Unfortunately we've implemented the virDomainBlockCopy API also using a flag-hack with the rebase api. Are you passing in VIR_DOMAIN_BLOCK_REBASE_COPY? If yes, then you in fact should use virDomainBlockCopy API which takes an XML which allows to specify also a network based disk. The support for block copy to a network destination will be added soon as I'm working on it. Without the VIR_DOMAIN_BLOCK_REBASE_COPY flag it should work as expect...

I'm currently running: virsh --version 1.0.2 libvirtd --version libvirtd (libvirt) 1.0.2 I have a couple questions. 1. Can I upgrade my libvirt.so version to use with an older libvirtd? In other words, does the versions of libvirt and libvirtd need to be in lock step? 2. I'm able to use virsh blockcopy, but I want to do it programmatically via C. I looked through the API and was not

...Is that we used; this is a good starting point for any other C binding, and also for any other language binding if you can map the C bindings over to your language bindings. In particular, tools/virsh-domain.c:cmdBlockCopy() is currently implemented atop the virDomainBlockRebase() API call with the VIR_DOMAIN_BLOCK_REBASE_COPY flag (but the door is open to also implement it atop a newer more-powerful virDomainBlockCopy() once we start targetting some of qemu 1.7 or 2.0's newer features). -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
