Update (20131106): Please see FreeBSD 10 On CloudStack + XenServer Blog post instead.
UPDATE (20131015): Major changes have gone into FreeBSD 10 including fixes for the xenbusb_nop_confighook_cb. BETA2 onwards would support XenServer out of the box. The ISOs are available at http://ftp.freebsd.org/pub/FreeBSD/releases/ISO-IMAGES/10.0/.
Pretty excited to have FreeBSD 10.0-CURRENT running under XenServer 6.1 in HVM mode using the XENHVM configs.
Follow the instructions in http://home.uncon.net/dokuwiki/doku.php?id=xenserver:freebsd to workaround the ‘xenbusb_nop_confighook_cb’ issue on boot-up. UPDATE (20131015):This is now fixed with r256423
The steps in a nutshell:
- Download a very recent CURRENT snapshot ISO from http://ftp4.freebsd.org/pub/FreeBSD/snapshots/amd64/amd64/ISO-IMAGES/10.0/
- Create a new ‘other‘ VM using Citrix XenCenter UI from the snapshot ISO
Build and install the XENHVM kernelUpdate (20130927): Latest FreeBSD 10 Current has XENHVM merged into the GENERIC kernel and works well with the fully open source XenServer 6.2 release. When FreeBSD 10 is officially released, it should work out of the box- Fix up ‘rc.conf‘ and ‘fstab‘ to use the Xen virtual devices
- Install the Xen tools from ports
- Shutdown the VM
- Destroy the CDROM VBD device
- VM Start
It would be nice if Citrix were to officially support stock FreeBSD installation at some point. Their NetScaler product is actually based on FreeBSD. In the meantime, thanks to the FreeBSD Xen community on making the OS work on EC2 and thus XenServer. Update (20130927): Most of the recent updates to FreeBSD -CURRENT to support Xen has been contributed by Citrix.
