My kvm virtual machines are Ubuntus and Windows 10. All went well as far my host Ubuntu 14.04 updated its kernel to 3.13.0-151. After that both Ubuntu and Windows 10 virtual machines crash on boot. If I boot host with kernel 3.13.0-149, virtual machines work OK as they have used to do for years. Host uses amd 64 bit processor. Boot log as a screenshot to boot Ubuntu 16-04 guest is as an attachment. Host kernel is Ubuntu 14.04 with last current kernel, vmlinuz-3.13.0-157, but problem started from kernel 3.13.0-151 and continues in all kernels newer than 3.13.0-149. Kernel 3.13.0-149 runs all guest, linux or windows, OK. -- You are receiving this mail because: You are watching the assignee of the bug.
