Image: i386-virt.
VyOS now works with XenServer. We installed XenTools and checked migration, seems to work fine.
Before this image something was wrong with our initramfs-tools build, the script that is responsible for loading Xen modules was missing, and we were wondering why the drives and NICs are not detected. Now it gets included properly and modules load at boot when running in Xen. Thanks to Mamizou for help with understanding Xen drivers, and Alexey Blinkov for testing it on his setup.
