qemu + spice-server in 6.4 now support live migration together with spice's native USB redirection. Spice's native USB redirection is already support in RHEV-M, bit when it is used live migration is disabled for the vm. For RHEV-M 3.2 this means that: 1) Live migration should be allowed for vm-s using Spice's native usb redirection when both the source and target hosts are rhel 6.4 based *and* seamless migration (*) is enabled. 2) When creating a new vm on a 6.4 based RHEV-H, RHEV-M should default to native usb and must no longer warn that using native usb will break live migration 3) We should seriously consider to simply not allow using the old usb support when creating a new vm on a 6.4 based RHEV-H Components involved from the spice side: -qemu-kvm -usbredir -spice-server -spice-gtk *) Note that live-migration with native usb redirection is possible without seamless migration too, but then any redirected usb devices will be disconnected from the guest upon migration.
ad 2) see BZ 889551 ad 3) - is that in works as well? Any tentative target date? We'd be happy to get rid of legacy USB.
