[Qemu-devel] git master endless migration

Stefan Priebe - Profihost AG Fri, 08 Feb 2013 02:30:34 -0800

Hello list,

while testing current git master
(ecd8d4715ea33aa2c146a5047bacb031e86af599) i've seen a VM endless
looping - the monitor socket also did not answer anymore while
migrating. The VM was under very low load but the migration never
finishs and the VM was not accessable anymore. Is this a known issue?


An strace looked like this:
