Radim, Would you please provide your test setup? So that I can try to reproduce it on my machine and debug it. > The setup from Igor's latest x2APIC QEMU patches creates two VCPUs, > first has id 0 and second has 280.

Not sure whether this is related to the v5 fix on kernel EOI hack (the two patches that you have reviewed)? That two patches should solve the level-triggered interrupt issue that I have encountered, like e1000 cards. -- peterx
