I want to switch form my old Intel platform to new Ubuntu 18.04 LTS + Ryzen 2700 + Asus X470 F Gaminng mobo. Virtualization is a must for me. So after installing clean Ubuntu I've installed KVM + QEMU.
When I run Ubuntu 16.04 just live CD in virtual machine it is painfully slow. It turns on in about 5 minutes.
But running Ubuntu 18.04 live CD in virtual machine works as I expect it to be - super fast.
I have enabled IOMMU and SVM in bios and command
KVM acceleration can be used
I've tried to change Video to different modes (QLX, VGA etc) - nothing changes.
I've tried to change emulated CPU to Broadwell, Haswell, and few other options - nothing changes.
Any suggestions where to look to resolve this issue?
