Softlockups are a symptom that a guest vcpu hasn't been able to execute. Unfortunately I don't see anything that points to a specific bug in the backtraces. > If needed, I can provide further debugging information, bisect etc... It looks like your guests are SMP. How many vcpus are you running? How many physical cpus does /proc/cpuinfo list on the host? Is the host overloaded when this occurs? Are there any clues in host dmesg?
