What’s the output of xm info in dom0, particularly hw_caps and xen_caps.

What’s output of /proc/cpuinfo.


The way you have the system configured, the system doesn’t recognize that your system is capable of running paravirtualized xen.  This could be a misconfigured libvirtd or wrong version of libvirtd tools, or a misconfigured kernel that is not sending the right flags to xm info.


Also, what’s uname –a of your kernel in dom0.

Hello Community,

 I successfully installed and run xen (xm list and xm info can output appropriately).
 However, while I was installing domU image by using virt-install -p at domU OS. I encountered an
error information" Host does not support virtualization type 'xen' ".
I built xen from source. Some of my friends have the same issue, but if they use pre-build xen, the issue will go away.
However, I want to insist in using my version of xen (build from source). Does anyone can give any hint about this error?

I'll appreciate if any suggestions can be given,
