I've been able to get a FreeBSD 8 Xen PV domU running successfully on RedHat 5; however, when I try to run the same image under NetBSD Xen, I get a kernel panic. If I comment out the 'vif' line it boots, but I have no network obviously. I've got a RedHat domU that I moved as well, and it works perfectly under NetBSD. The guest: uname -a FreeBSD fbworkstation 8.0-RELEASE-p2 FreeBSD 8.0-RELEASE-p2 #0: Fri Apr 9 18:57:44 UTC 2010 root@freebsdxen:/usr/obj/usr/src/sys/XEN i386 The host: uname -a NetBSD vdesktop 5.0.2 NetBSD 5.0.2 (XEN3_DOM0) #0: Sat Feb 6 13:44:13 UTC 2010 builds@b8.netbsd.org:/home/builds/ab/netbsd-5-0-2-RELEASE/amd64/201002061851Z-obj/home/builds/ab/netbsd-5-0-2-RELEASE/src/sys/arch/amd64/compile/XEN3_DOM0 amd64 The console message: xn0: <Virtual Network Interface> at device/vif/0 on xenbus0 xn0: bpf attached xn0: Ethernet address: 00:16:3e:68:d8:55 WARNING: WITNESS option enabled, expect reduced performance. panic: mutex ??????/?5? not owned at /usr/src/sys/vm/vm_page.c:425 cpuid = 0 KDB: enter: panic [thread pid 12 tid 100023 ] Stopped at kdb_enter+0x3a: movl $0,kdb_why db> I'd be happy to provide any further details, and even step through the debugger if someone could tell me what to look for.
