...'s config file. Instead, I get the error message in libvirtd.log that: warning : x86Decode:1346 : Preferred CPU model Nehalem not allowed by hypervisor; closest supported model will be used If I review the qemu log for that particular domain, I see that my CPU has been changed to this: -cpu kvm64,+lahf_lm,+popcnt,+sse4.2,+sse4.1,+ssse3 (in other places, I see it set to core2duo rather than kvm64) However, it *should* be Nehalem. For some background, I'm running kvm on a westmere proc, which is the successor to Nehalem. I'm specifying Nehalem as the target platform, though, to ma...

...PU host which is an Intel Xeon E5410 and my problem is that this CPU is detected only with the cpumodel "pentium3". But if use the kvm -cpu ? command, it returns me the following capabilities : $ kvm -cpu ? x86 qemu64 x86 phenom x86 core2duo x86 kvm64 x86 qemu32 x86 coreduo x86 486 x86 pentium x86 pentium2 x86 pentium3 x86 athlon x86 n270 Moreover, if i decide to use the pentium3 cpumodel for my KVM VM, the CentOS freeze during its loading. My libvirt and kvm are t...

...blow up everyone's email on this but I tried something new and found a different problem. I uninstalled all the debian package (libvirt, kvm, qemu, virt-manager, etc.) and then remade all the packages and installed them. Haswell again shows up in virt-manager, but now any CPU I choose including kvm64 and qemu64 give the same error: root@mal:~# virsh create /etc/libvirt/qemu/debian7-nonsmp.xml 2013-06-19 03:09:42.836+0000: 24248: info : libvirt version: 1.0.6 2013-06-19 03:09:42.836+0000: 24248: warning : virLogParseDefaultPriority:1581 : Ignoring invalid log level setting error: Failed to crea...

...e with the host CPU. I would like to further limit the list to CPUs of the same vendor as the host CPU. How can I do that? I tried to use virConnectBaselineCPU with <vendor> element and checking whether I obtain the same CPU, but that doesn't filter out CPUs without any vendor such as `kvm64' or `pentium'. Thanks, Milan

...rivers obtained from running the spice guest tools vs. the virtio-win stuff. I use: http://www.spice-space.org/download/windows/spice-guest-tools/spice-guest-tools-0.100.exe I did have problems with blue screens at boot (to even get the installation going) until I changed the CPU type to "kvm64" -Greg

Hi Everyone, Has anyone managed to install Windows 10 tech preview build 10130 as a KVM on a CentOS 6 host? I'm having problems that I haven't been able to get past. I can get the CD to boot and the install process to begin, but Windows keeps complaining about missing drivers. I've unsuccessfully tried the VirtIO ISOs from the Fedora project. The images I tried were:

@Michal: Thanks for your reply! Indeed I have found a package in the AUR (libvirt-zfs) and only had to change to the current version and add zfs-utils as dependency in the PKGBUILD. Now I don't get the previous error anymore but I still cannot setup a VM because I constantly get errors due to wrong permissions. I have tried to change the permissions in: - /etc/libvirt/qemu.conf -
