September 4, 201510 yr Hi, I recently upgraded my version of unraid from v6.0-beta14 to 6.1.0. I was previously using xen to run a couple of virtual machines. Since upgrading, obviously my xen VM's are no longer available so I went to install KVM. However, for some reason unraid doesn't seem to detect the capabilities of my CPU which according to this page http://ark.intel.com/products/80806/Intel-Core-i7-4790-Processor-8M-Cache-up-to-4_00-GHz should support this feature. cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 60 model name : Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz stepping : 3 microcode : 0x17 cpu MHz : 3600.112 cache size : 8192 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 1 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 13 wp : yes flags : fpu de tsc msr pae mce cx8 apic sep mca cmov pat clflush acpi mmx fxsr sse sse2 ss ht syscall nx lm constant_tsc rep_good nopl nonstop_tsc eagerfpu pni pclmulqdq monitor est ssse3 fma cx16 sse4_1 sse4_2 movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand hypervisor lahf_lm abm ida arat pln pts dtherm fsgsbase bmi1 hle avx2 bmi2 erms rtm xsaveopt bugs : bogomips : 7200.22 clflush size : 64 cache_alignment : 64 address sizes : 39 bits physical, 48 bits virtual power management: processor : 1 vendor_id : GenuineIntel cpu family : 6 model : 60 model name : Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz stepping : 3 microcode : 0x17 cpu MHz : 3600.112 cache size : 8192 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 1 apicid : 1 initial apicid : 1 fpu : yes fpu_exception : yes cpuid level : 13 wp : yes flags : fpu de tsc msr pae mce cx8 apic sep mca cmov pat clflush acpi mmx fxsr sse sse2 ss ht syscall nx lm constant_tsc rep_good nopl nonstop_tsc eagerfpu pni pclmulqdq monitor est ssse3 fma cx16 sse4_1 sse4_2 movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand hypervisor lahf_lm abm ida arat pln pts dtherm fsgsbase bmi1 hle avx2 bmi2 erms rtm xsaveopt bugs : bogomips : 7200.22 clflush size : 64 cache_alignment : 64 address sizes : 39 bits physical, 48 bits virtual power management:
September 4, 201510 yr XEN isn't supported at all in any finalized version of unRAID. Are you sure you have vt-d enabled in BIOS?
September 7, 201510 yr That's probably it... I'll have a look.. What did you find? Just curious if this is still an issue. Edit: if I don't hear from you soon, I or another will move this to General Support. We can always move it back if needed.
September 8, 201510 yr I'm going to wager that this simply wasn't enabled in his BIOS. Probably had linux-only guests when he was using Xen, which doesn't require any hardware-based virtualization to work. KVM requires it for ALL guests.
August 15, 20169 yr I recently upgraded from 6.0 to 6.1.9 and am having this same issue, but I'm not home to check the bios at the moment. Previously I had a Win vm setup under zen not to mention the fact that my hardware clearly supports vt-x. Any other things I could try if it's not the bios issue?
August 17, 20169 yr It wasn't bios for me. I still had a setting for starting unraid with zen set. Once I started normally, KVM was enabled in unraid.
