Hi Thomas, Basically KVM <hidden state=on/> equals kvm=off, so you can keep it.
And there is no need to reinstall NVIDIA driver whenever you change XML code. If you already tried remove Hyper-V features and still got Code 43, there're few ways you can try. 1. Set CPU as "host-passthrough" mode 2. You can type virsh capabilities to see how many machine type you can use, and try different i440fx version. Some GPU may got a problem if using higher version of i440fx I'm running K420 on server, and guest OS is Windows 7. But I'm not using third-party ppa to install newer QEMU and libvirt, all I do is compile and install by myself. Using OVMF and i440fx-2.6 and it works perfectly without Hyper-V (Because Windows 7 can't enable Hyper-V in OVMF mode.) I'm not sure these tip works on you or not, just give it a try :) 2016-11-17 9:40 GMT+08:00 Thomas Mashos <tho...@mashos.com>: > Hi Eddie, > > XML Dump is here http://termbin.com/mwwd it's a Windows 10 Home 64-bit > guest.
