I still observe this "slowness" with kvm-86 after the guest is

Anything in guest dmesg?
No.
No hints in syslog, dmesg...
Can it be that this is more likely to happens on "busy" hosts?
We'll only know once we fix it...
It happens for me on a host where I have 16 guests running.
Also, as I booted the host almost 2 days ago, 2 or 3 guests didn't
start properly (16 guests were starting at the same time), with their
kernel saying:
Kernel panic - not syncing: IO-APIC + timer doesn't work!
Can it be related?
After I restarted these failed guests, they started properly.
This is timing related. On a busy host you can get timeouts and thus
the panics. It's unrelated.
Maybe virtio is racy and a loaded host exposes the race.
