請問~~我的KVM不能跑paravirt~~但是可以跑hvm~~~為神麼??CPU明明有支援~~~以下是egrep '(vmx|svm)' /proc/cpuinfo所出來的東西~~

再創建paravirt時就會出現以下畫面
ValueError: Host does not support virtualization type 'xen'

這是我還有神麼套件沒裝嗎??

KVM 不太熟 @@，
或許可回覆到官方 mial list~

您好:

可以提供更多詳細的資料嗎? Linux Dist ? Kernel Ver ? 以便判斷何處支援出問題.
用 KVM 去跑 paravirt 其 kernel 版本至少要在 2.6.25 以上.

Linux Kernels from 2.6.25 and later come with built in paravirtual network and block device drivers so that they can run as paravirtual guests on KVM host running on release 60 or later. For older linux guest kernels than 2.6.25, the recently released linux paravirtual drivers will have to be downloaded and installed.

Thanks

我秀UNAME的結果~~~
Linux ubuntu 2.6.32-23-server #37-Ubuntu SMP Fri Jun 11 09:11:11 UTC 2010 x86_64 GNU/Linux
都合格阿~~~><"~~~就是不知道為神麼不能跑阿~~~><"~~

Hi,

im running 4x12cores opteron kvm guests at work true cores,not hyperthreading, so i can make test for you if you want .
