Re: [libvirt] [PATCH] qemu: Fix a possible deadlock in p2p migration

Two more calls to remote libvirtd have to be surrounded by qemuDomainObjEnterRemoteWithDriver() and qemuDomainObjExitRemoteWithDriver() to prevent possible deadlock between two communicating libvirt daemons. See commit f0c8e1cb3774d6f09e2681ca1988bf235a343007 for further details. --- src/qemu/qemu_driver.c | 18 ++++++++++++++++-- 1 files changed, 16 insertions(+), 2 deletions(-)
