You need to specify a root= entry that matches the root device - the kernel doesn't know where to find the device to mount the / directory. -Nick -----Original Message----- From: Yassine AYACHI <ayachi.yassine@xxxxxxxxx> To: Nick Couchman <Nick.Couchman@xxxxxxxxx> Cc: Xen-users@xxxxxxxxxxxxxxxxxxx Subject: Re: [Xen-users] kernel BUG !! Date: Tue, 25 Nov 2008 17:20:21 +0100 Thanks for replay, 1) CentOS release 5.2 (Final) 2) version 3.0.2 installed by yum 3)Red Hat Enterprise Linux ES release 4 (Nahant Update 7) 4) I tried with all proposed kerlens kernels 2.6.9-78, 2.6.9-78, 2.6.9-55 but they all generate the following error : Waiting for driver initialization. Scanning and configuring dmraid supported devices Scanning logical volumes Reading all physical volumes. This may take a while... No volume groups found Activating logical volumes Volume group "VolGroup00" not found Creating root device. Mounting root filesystem. mount: could not find filesystem '/dev/root' Setting up other filesystems.

PS. How Is it possible to boot with a minimal kernel Cheers 2008/11/25 Nick Couchman <Nick.Couchman@xxxxxxxxx> A few questions: 1) What update of CentOS5 are you using on the host? 2) Are you using the Xen version that came with CentOS5, or have you manually installed another version? 3) What update of RHEL4 are you running as the guest? 4) The kernel version referenced in the error message indicates that you have a pretty old kernel - 2.6.9-42, while the more recent RHEL releases are on 2.6.9-78 (the latest) or 2.6.9-67. You may want to try booting a minimal system in your domU and updating the kernel to a later version and see if that helps. -Nick I'am trying to run a Red Hat Enterprise Linux ES release 4 VM on a centos5 host ... the boot seems gonig without problem, but towards the end I have this error : ------------[ cut here ]------------ kernel BUG at arch/i386/mm/ioremap-xen.c:32! invalid operand: 0000 [#1] SMP Modules linked in: md5(U) ipv6(U) autofs4(U) i2c_dev(U) i2c_core(U) sunrpc(U) ib_sdp(U) ib_ipoib(U) rdma_ucm(U) rdma_cm(U) ib_local_sa(U) findex(U) ib_addr(U) ib_uverbs(U) ib_umad(U) ib_ucm(U) ib_sa(U) ib_cm(U) ib_mad(U) ib_core(U) dm_snapshot(U) dm_zero(U) dm_mirror(U) dm_mod(U) ext3(U) jbd(U) CPU: 0 EIP: 0061:[<c01132e1>] Not tainted VLI EFLAGS: 00010206 (2.6.9-42.0.3.EL.xs0.4.0.263xenU) EIP is at direct_remap_area_pte_fn+0x19/0x6e eax: d85ae000 ebx: c130b5a0 ecx: e9000003 edx: 50680000 esi: d85ae000 edi: daa72f28 ebp: d85ae000 esp: daa72eb4 ds: 007b es: 007b ss: 0068 Process dchcfg32 (pid: 2027, threadinfo=daa72000 task=ddf4cc30) Stack: c130b5a0 000185ad 00000000 d85ae000 c0149100 daa72f28 b4600000 b460b000 b460b000 daab7010 dae2b840 00010000 b45fb000 d8590000 00007ff1 c01134b5 c01132c8 daa72f28 0000000f d8590100 000f0000 000ef025 00000000 b45fb000 00010000 00000001 000000f0 00010000 dae2b840 d8590050 dac33284 dac33284 Call Trace: [<c0149100>] apply_to_page_range+0x197/0x1de [<c01134b5>] __direct_remap_pfn_range+0x17f/0x1cf [<c01132c8>] direct_remap_area_pte_fn+0x0/0x6e [<c01ee811>] xen_mmap_mem+0x4a/0x52 [<c014be44>] do_mmap_pgoff+0x48c/0x671 [<c010d987>] sys_mmap2+0x7e/0xaf [<c02564f7>] syscall_call+0x7/0xb [<c025007b>] unix_stream_sendmsg+0x147/0x33a Code: 79 fc ff ff 51 e8 04 b4 0a 00 59 e9 6d fc ff ff 90 90 55 57 56 89 c6 53 89 d3 8b 10 8b 7c 24 14 8b 48 04 85 d2 75 04 85 c9 74 08 <0f> 0b 20 00 04 c4 26 c0 89 da 8b 2f 2b 15 50 1a 36 c0 c1 fa 05 <0>Fatal exception: panic in 5 seconds Kernel panic - not syncing: Fatal exception and it reboot indefinitely someone know what it is ?
