I'm trying to add a virtual machine using Virtual Machine Manager 0.8.5 but when I select *New* I receive the following: Warning: Host does not appear to support hardware virtualization. Install options may be limited. According to this link (s.b. one line) it does. http://www.cpu-world.com/CPUs/K10/AMD-Phenom%20II%20X2%20560%20-%20HDZ560WFK2DGM%20%28HDZ560WFGMBOX%29.html;. Now according to another webpage the AMD processor must have the flag svm to have virtualization. My CPU does NOT have that flag but it does have one called hypervisor. Hmm, not sure what the hypervisor flag is, but virtinst is looking for vmx or svm reported in libvirt capabilities Could be as simple as adding hypervisor to the list of acceptable flags, but I wouldn't put a paycheck on that guess ;) After some googling, I found this debian bug report: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=604160 Seems like hypervisor just means you are booted into xen, and doesn't say anything about whether fullvirt is supported. Does booting into a regular kernel show svm in cpuinfo? Anything interesting in 'xm dmesg'? When running under Xen you need to use xm info and check the caps if you can run HVM (hardware virtualized) or not. Dom0 Linux kernel won't see the cpu flags in /proc/cpuinfo since dom0 is a VM, and the hypervisor is hiding the flags from VMs. (at least until Xen Nested Hw Virt is merged, which should be soon). Other option is to read xm dmesg for supported features: http://wiki.xen.org/xenwiki/XenCommonProblems#head-39c253c76df6f0fa4fb7ff4769cc733284bac9cb -- Pasi -- xen mailing list xen@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/xen
[Fedora-xen] virtinst: do I have virtualization or not?
Hi all, Using f14-x86_64 installed from the LiveCD with myoung's f12-xendom0. It boots both standalone and with xen. /sys/hypervisor is populated. /proc/cpuinfo reports CPU is AMD Phenom II X4 B60 Black Edition. Virtualization is [ENABLED] in the BIOS. I'm trying to add a virtual machine using Virtual Machine Manager 0.8.5 but when I select *New* I receive the following: Warning: Host does not appear to support hardware virtualization. Install options may be limited. According to this link (s.b. one line) it does. http://www.cpu-world.com/CPUs/K10/AMD-Phenom%20II%20X2%20560%20-%20HDZ560WFK2DGM%20%28HDZ560WFGMBOX%29.html;. Now according to another webpage the AMD processor must have the flag svm to have virtualization. My CPU does NOT have that flag but it does have one called hypervisor. The question becomes will this CPU work with Xen?. If it will, does this mean there is a bug in virtinst? Can I ignore the warning? Thanks for any help, Mike Wright -- xen mailing list xen@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/xen

If you recently enabled virt in the bios, make sure you fully turn off your machine and let it sit for a couple minutes (yes this can actually make a difference with bios settings). Additionally check your motherboard manufacturer website and make sure your board supports your CPU and has the latest bios update installed. - Cole -- xen mailing list xen@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/xen
