Hi, Thimo, I cannot reproduce this issue in my box after running about two weeks: I started four guests (two PV guests and two HVM guests). And each guest runs a simple workload (ping a remote machine). After two weeks, the machine still works no crash and panic happen. Are there any special workload required to reproduce this issue? Attached the cpuinfo and pci info in my box. Please compare it with yours to see whether it is same. Especially, the microcode version. Best regards, Yang Attachment:
