	~~==== <code>error: device model qemu-dm is not executable: No such file or directory</code> ====~~

	This error follows a <code>qemu-xen is unavailable, using qemu-xen-traditional instead</code> message. This is an upstream bug in Xen, and can be fixed by pull request {{pull\|365890}}, or by overriding the QEMU path in your domain configuration:

	~~{{file\|example-hvm.cfg\|cfg\|~~
	~~<nowiki>~~
	~~device_model_override='/run/current-system/sw/bin/qemu-system-i386'~~
	~~</nowiki>~~
