It doesn't issue any normal shutdown commands, but tells the Xen code in the kernel to start a shutdown. It's broken on the kernel side. kern/171118 Also, NetBSD's workaround for this is to enable powerd, but we can't when we're running XENHVM and I suspect their powerd is a completely different beast. I can confirm this as a problem as well, on x86 64bit PVM. FreeBSD VM sits at "press any key to reboot". Soon as I press any key, then the VM shuts down. I don't recall why, but something made me think that FreeBSD was responding to a VM shutdown with 'shutdown -h now' when it should be responding with 'shutdown -p now", which seemed to work correctly. - If you use PF with Xen HVM your performance will suck. Known bug. kern/154428 Set net.inet.tcp.tso=0 as a workaround. We don't use PF under Xen, so can't comment. - "Deactivating" a network interface is an option after enabling the xe-guest-utilities scripts. Please don't do that. It seems to cause a panic every time. kern/171138 Also, this happens when you try to change the VLAN assigned to an interface. We have not tried this, good to know. Additional bugs.... I believe all mentioned here already.... 1) 64bit PVM won't mount filesystems, after install have to change fstab adpXpY references to adXpY (or something similar, don't have it in front of me). 2) 64bit PVM won't boot with a virtual CD/DVD drive attached, have to remove it from the command line. I know there's other bugs, but the above ones are pretty much show-stoppers for getting freebsd up under XenServer. Fortunately, there's workarounds.

I've mentioned it. The domU tools scripts are being redesigned to be = more platform agnostic and a guy on that team at Citrix has been having = me assist him with figuring out how to pull data in the format he needs = as there are new features coming to XenServer. It looks like Citrix has = interest in FreeBSD because a client wants to do a large deployment, and = NetBSD will be easy too. They want these tools to be in FreeBSD ports = and NetBSD's pkgsrc, so it will be well integrated with the community = and the way the OS already is maintained. It just sounds like Citrix = will be pushing patches to the port maintainer in the future (unless = they take it over themselves). Overall, things are looking bright for FreeBSD/Xen users.
