by silviu d
Hello,
I was wondering if there is a way to execute commands from dom0 into domU
without loging into domU with ssh.
thanks

Was xenstored.service enabled? That should have set up the environment
correctly.

One of the experiments I was intending to do with that build was to see if
xen would would work with Fedora's qemu. As you have just discovered the
answer is no, though the tools configuration option allowing you tell xen
where to find it seems to work. If you uninstall the qemu-system-x86
package or add the line
device_model_version="qemu-xen-traditional"
to your configuration file then your hvm guest should boot.
