Hi, I've installed qemu 2.5 through the package manager. There is a bug which blocks making an external snapshot for the second time. A fix is released: https://lists.gnu.org/archive/html/qemu-devel/2016-01/msg06163.html I thought, why not download the source, apply the patch, build + make and then copy qemu-system-x86_64 to the /usr/bin/ folder..... But if I do 'virsh start my_vm', I get these errors: fout: internal error: early end of file from monitor, possible problem: warning: host doesn't support requested feature: CPUID.80000001H:ECX.svm [bit 2] warning: host doesn't support requested feature: CPUID.80000001H:ECX.svm [bit 2] qemu: could not load PC BIOS 'bios-256k.bin' First: What can I do about the 'host doesn't support requested feature'? Second: I think the compiled binary doesn't look for the bios-256k.bin in the right place? Help wil be much apreciated... Greetings, Dominique.
