could not find capabilities for arch=x86_64 domaintype=kvm

 Hi,

I am new  to Libvirt and Qemu.I have installed Libvirt 6.10 and qemu-kvm 4.2.0 on CentOS8.

I configured and built libvirt based on instructions from

https://libvirt.org/compiling.html.

But when i tried to create a VM using virsh it shows the following error:

# virsh create /home/abc.xml
error: Failed to create domain from /home/abc.xml
error: invalid argument: could not find capabilities for arch=x86_64 domaintype=kvm

When i check the hypervisor capabilities ,it doest show qemu in guest domain type.

# virsh capabilities

As per the reply from this mailing-list i passed an option while building the libvirt.

ie.,

meson build -Dsystem=true

It worked for me.

But Now, i tried to migrate my work on a new machine with same os and same version as above.

As part of,I configured and built libvirt.Also passed meson build -Dsystem=true while building libvirt.

After installation I tried with 
# virsh create /home/abc.xml

It results in the same error shown below.

error: Failed to create domain from /home/abc.xml
error: invalid argument: could not find capabilities for arch=x86_64 domaintype=kvm

I stuck here.

Thanks for the help in advance.
