Thank you very much for your list of bugs. I am running FreeBSD 8.2/9.0 (amd64 XENHVM) on XenServer 5.6SP2/6.0.2/6.1, feld> Also, if you aren't aware, here is my personal list of Xen bugs: feld> feld> - Shutdown via Xen fails to poweroff. It doesn't issue any normal shutdown commands, feld> but tells the Xen code in the kernel to start a shutdown. It's broken on the kernel feld> side. kern/171118 feld> Also, NetBSD's workaround for this is to enable powerd, but we can't feld> when we're running XENHVM and I suspect their powerd is a completely different beast. feld> feld> - If you use PF with Xen HVM your performance will suck. Known bug. feld> kern/154428 feld> Set net.inet.tcp.tso=0 as a workaround. It might be better to disable rxcsum, txcsum, and lro, too. My understanding is the point is the 'NIC hardware' is not the real one but emulation by Xen Host, so that those 'off loading' makes context switch storm between domU and dom0. # please kindly correct me if wrong. feld> - "Deactivating" a network interface is an option after enabling the xe-guest-utilities scripts. feld> Please don't do that. It seems to cause a panic every time. kern/171138 feld> Also, this happens when you try to change the VLAN assigned to an feld> interface. - FreeBSD 9.0 XENHVM panics during boot sequence if it runs on XenServer 6.1. Remove (virtual) CD/DVD drive from guest configuration. http://list-archives.org/2012/10/10/freebsd-xen-freebsd-org/xenbusb_nop_confighook_cb-timeout/f/4227874455 And Yes, I have some experience successful live-migration with those ports. Special Thanks to author! Thank you!! looking forward to FreeBSD 9.1 and Citrix official xen-tool for FreeBSD :-) -- moto kawasaki <moto@kawasaki3.org> 090-2464-8454
