Hi, I have installed FreeBSD 8.1-STABLE paravirtualized Xen DomU according = to the documentation at: http://forums.freebsd.org/showthread.php?t=3D10268 RELENG_8 CVS tag was used to get world and kernel sources. The kernel get into panic while booting: ---- panic: HYPERVISOR_update_va_mapping(((unsigned long)(va)), (pa | 0x002 | = 0x001 | pgeflag | pmap_cache_bits(mode, 0)), UVMF_INVLPG| UVMF_ALL) < 0: = /usr/src/sys/i386/xen/pmap.c:1269 cpuid =3D 0 KDB: enter: panic [thread pid 0 tid 0 ] Stopped at kdb_enter+0x3a: movl $0,kdb_why db>=20 db> where Tracing pid 0 tid 0 td 0xc03e0af0 kdb_enter(c036c678,c036c678,c0390af5,c051ecb4,0,...) at kdb_enter+0x3a panic(c0390af5,c0398fbf,c0398cd1,4f5,0,...) at panic+0x134 pmap_mapdev_attr(0,0,500,6,c051ed44,...) at pmap_mapdev_attr+0x13d pmap_mapbios(0,0,500,1,c051ed44,...) at pmap_mapbios+0x27 x86bios_call(c22ca3c0,0,0,76,c051ed64,...) at x86bios_call+0x212 module_register_init(c03db8f0,7020800,7020800,523000,0,...) at = module_register_init+0xa7 mi_startup(523000,0,0,0,0,...) at mi_startup+0x96 btext() at btext+0x95 ---- DomU details FreeBSD 8.1-STABLE #8 kernel config: /usr/src/sys/XEN i386 xen config: ---- kernel =3D "/var/lib/xen/images/kernel.6jZmCCXlzjBa" memory =3D "512" name =3D "6jZmCCXlzjBa" vcpus =3D "1" vid =3D "17" sanip =3D "10.200.200.19" vif =3D [ 'mac=3D00:16:3e:0a:e2:40, bridge=3Dxenbr0, ip=3D68.169.47.45, = vifname=3D6jZmCCXlzjBa, rate=3D0Mb/s' ] disk =3D [ 'phy:/dev/iscsi_0_17,sda,w', 'phy:/dev/iscsi_0_137,sdb,w' ] extra =3D "boot_verbose=3D1" extra +=3D ",vfs.root.mountfrom=3Dufs:/dev/da0" extra +=3D ",kern.hz=3D100" ---- Dom0 details CentOS release 5.4 (Final) Linux vl-radar-box1.slc.westdc.net 2.6.18-164.6.1.el5xen #1 SMP Tue Nov = 3 16:48:13 EST 2009 x86_64 x86_64 x86_64 GNU/Linux xen-3.0.3-94.el5_4.2 DomU built from RELENG_8_0 booted fine for me.
