Otherwise, I'm curious if you have any insight into where we're
pausing for 10ms that's causing the missed interrupt?
Don't know yet.
What's your full command line?
/home/gleb/install/qemu/org/bin/qemu-system-x86_64 -hda Windows2003.raw -m 1024
-net
nic,model=rtl8139 -net user -vnc 172.17.10.111:1 -usbdevice tablet
-usbdevice tablet may be the culprit. Is the guest doing an significant IO?
-usbdevice tablet has nothing to do with it. Qemu misses interrupt even
without this option and with SDL screen it misses them in bunches when
SDL redraws a screen. In case of vnc qemu misses interrupt because of
fsync() call in raw_flush(), or so my instrumentation shows.
