Hi, thanks for the info! It seems quite stable now, but I haven't tried -smp 2 yet.
Timing problems seem plausible: I have a dvb-card passed through to the guest. With normal setup, the frontend detection of the driver module breaks every other try with a i2c timeout. I changed the cpufreq governor of the host from ondemand to performance, and the guest seemed stable, until suddenly the timeouts filled the logs again. Until now, with clocksource=acpi_pm, I saw only occasional irq timeouts of the card (like, under 10 in 30 minutes), under heavy load of the guest.
