Hi, I had a C7 virtual machine running on a C7 host for several weeks without any problems. Today I rebootet the host and now the virtual machine does not start anymore. I can see grub coming up and starting the kernel. After some seconds the last thing that is visble on the VM console is "ss perfctr msr (MSR c1 is0)" then the screen goes blank with just a blinking cursor in the upper left corner. After that nothing happens anymore. The CPU load on the host is nearly 0%. Any ideas what could be the reason and how to solve this? Best regards, Bernd
