Is igbvf loaded in the host? No, I don't load igbvf driver in host. >Is the vf attached to igbvf or pci-stub or nothing? VF is attached to 'pci-stub' in host. >Can we narrow down the kvm.git commit range at all? The > one provided is over 12k commits covering v3.4-rc3 to v3.5-rc6. Thanks I did more testing. Do you remember the bug #43328 ( VT-d/SR-IOV totally doesn't work in guest)? Just use your fix commit for that bug, I'll meet this hot-plug issue. Is there a chance your patch fixed one bug but introduced another one? :) commit a76beb14123a69ca080f5a5425e28b786d62318d Author: Alex Williamson Date: Mon Jul 9 10:53:22 2012 -0600 KVM: Fix device assignment threaded irq handler -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.
