HWACCM: AMD-V features= 0 , opteron 2210
Posted: 19. Aug 2009, 21:33
I am have tried VirtualBox 3.02 and 3.04 on Ubuntu 64 bit 9.04 and 9.10 (alpha)
with all combinations I get the following output in the log file (and no hardware virtualisation)
00:00:04.066 HWACMM: AMD cpu with erratum 170 family f model 41 stepping 2
00:00:04.066 HWACMM: cpuid 0x80000001.u32AMDFeatureECX = 1f
00:00:04.066 HWACMM: cpuid 0x80000001.u32AMDFeatureEDX = ebd3fbff
00:00:04.066 HWACCM: AMD-V revision = 1
00:00:04.066 HWACCM: AMD-V max ASID = 64
00:00:04.066 HWACCM: AMD-V features = 0
It is strange that virtualbox is unable to use the svm becasue it is picking up the SVM support of the CPU (AMD opteron 2210), see below extract from same log file.
00:00:03.474 SVM - AMD VM Extensions = 0 (1)
kvm with kvm_amd works fine on this machine, it runs XP at near native speed and turning off hardware support slows it to a crawl - about the same speed as virtualbox manages.
I have an Intel based laptop running almost the same setup and I am happy to say that virtualbox is working very well on that machine (with hardware support).
thanks for any help
