Re: [Xen-users] Host does not support virtualization type 'xen'
Hi Steve,
what do you mean by qemu-kvm? Do you mean I need to run a command "qemu-kvm -cpu"?
But it says the command couldn't be found. I am a newbie of Xen, so please correct me if I misunderstood something.
Here is the result from virsh capabilities:

Do you think the output is normal?

I think the reason that virt-install doesn't want to do
a paravirtualized install on this machine (virt-install -p)
is because xm info is listing "virt_caps :hvm"
i.e. only hardware virtualization supported.
I am not sure how you would change that. the version of Xen
I run doesn't list a virt_caps field at all in xm info.
But I am almost positive that if the virt_caps field
is there, virt-install will look at it and not like it.
There are probably the output from some virsh commands you
could do to, such as virsh capabilities.
what does
qemu-kvm -cpu ?
tell you?

How can I check if the libvirtd is correctly configured or if other things
have been misconfigured?
Thanks in advance,

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

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.

Subject: [Xen-users] Host does not support virtualization type
'xen'
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,
Thanks,
