Host Support Status


The releases kvm-51 to kvm-53 fixed many AMD bugs. If kvm-53 (or newer) doesn't work for you, try out the kernel modules from kvm-53 (or later) and userspace from kvm-44. As usual, please also try the -no-kvm-irqchip and -no-kvm separately and report everything you see, including kernel logs (in /var/log/messages or /var/log/syslog).

On intel hosts, the main problem is with the real mode emulation, which happens in early stage of boot. If there's a failure as soon as the VM starts, it's most likely due to the real mode.
