Hi, On Xen-unstable I encountered this non stopping logspam while trying to shutdown an HVM domain with pci-passthrough: (XEN) [2015-04-24 11:55:47.802] io.c:164:d25v0 Weird HVM ioemulation status 1.

It did drop from it's assigned 3 vpcu's to 1 vpcu, but it stalled there. The log spam only stopped by destroying the guest. Since i haven't seen it before, it's probably hard to replicate. -- Sander _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
