Hi, I was trying to install Xen3.1.3 from source code on CentOS 5.5. Everything goes fine until I try to reboot my computer with the dom0. When I boot into the 2.6.18.8-xen kernel, I get a "Volume Group "VolGroup00" not found" ... "Kernel Panic" error and the computer restarts. Searching around, I found that this is something to do with missing drivers to read the logical volumes that I was using. However, I think I did include the drivers in the ramdisk, which was created with the command: "sudo mkinitrd -v -f --with=aacraid --with=sd_mod --with=scsi_mod --with=dm-mod --with=dm-mirror --with=dm-snapshot --with=dm-zero --with=iscsi_tcp --with=libata --with=ata_piix /boot/initrd-2.6.18.8-xen.img 2.6.18.8-xen". (I had to compile from source because CentOS5.5 seems to ship with Xen 3.0.3 which has a bug that affects live migration). Am I still missing some drivers? Thanks Virajith PS: Here is the output of "lsmod" from my non-xen kernel: Module Size Used by ipt_MASQUERADE 36801 3 iptable_nat 40773 1 ip_nat 53101 2 ipt_MASQUERADE,iptable_nat bridge 91889 0 drbd 245928 2 autofs4 63049 3 hidp 83649 2 rfcomm 104937 0 l2cap 89409 10 hidp,rfcomm bluetooth 118853 5 hidp,rfcomm,l2cap lockd 101553 0 sunrpc 199945 2 lockd cpufreq_ondemand 42449 1 acpi_cpufreq 47937 7 freq_table 38977 2 cpufreq_ondemand,acpi_cpufreq ip_conntrack_netbios_ns 36033 0 ipt_REJECT 38977 3 xt_state 35265 5 ip_conntrack 91621 5 ipt_MASQUERADE,iptable_nat,ip_nat,ip_conntrack_netbios_ns,xt_state nfnetlink 40457 2 ip_nat,ip_conntrack iptable_filter 36161 1 ip_tables 55201 2 iptable_nat,iptable_filter ip6t_REJECT 38849 1 xt_tcpudp 36289 18 ip6table_filter 36033 1 ip6_tables 50049 1 ip6table_filter x_tables 50505 8 ipt_MASQUERADE,iptable_nat,ipt_REJECT,xt_state,ip_tables,ip6t_REJECT,xt_tcpudp,ip6_tables be2iscsi 91477 0 ib_iser 69568 0 rdma_cm 68437 1 ib_iser ib_cm 72809 1 rdma_cm iw_cm 43465 1 rdma_cm ib_sa 74953 2 rdma_cm,ib_cm ib_mad 70629 2 ib_cm,ib_sa ib_core 104901 6 ib_iser,rdma_cm,ib_cm,iw_cm,ib_sa,ib_mad ib_addr 41929 1 rdma_cm iscsi_tcp 50637 0 bnx2i 74593 0 cnic 78425 1 bnx2i uio 45777 1 cnic cxgb3i 77489 0 cxgb3 214833 1 cxgb3i 8021q 57425 1 cxgb3 libiscsi_tcp 53317 2 iscsi_tcp,cxgb3i libiscsi2 77765 6 be2iscsi,ib_iser,iscsi_tcp,bnx2i,cxgb3i,libiscsi_tcp scsi_transport_iscsi2 74073 8 be2iscsi,ib_iser,iscsi_tcp,bnx2i,cxgb3i,libiscsi2 scsi_transport_iscsi 35017 1 scsi_transport_iscsi2 loop 48721 0 dm_multipath 56793 0 scsi_dh 42177 1 dm_multipath video 53197 0 backlight 39873 1 video sbs 49921 0 power_meter 47053 0 hwmon 36553 1 power_meter i2c_ec 38593 1 sbs dell_wmi 37601 0 wmi 41985 1 dell_wmi button 40545 0 battery 43849 0 asus_acpi 50917 0 acpi_memhotplug 40517 0 ac 38729 0 radeon 148193 0 drm 115560 1 radeon ipv6 435617 36 ip6t_REJECT,cnic xfrm_nalgo 43333 1 ipv6 crypto_api 42945 1 xfrm_nalgo parport_pc 62313 0 lp 47121 0 parport 73165 2 parport_pc,lp sr_mod 50789 0 cdrom 68713 1 sr_mod sg 70377 0 snd_hda_intel 639265 1 snd_seq_dummy 37061 0 snd_seq_oss 65473 0 snd_seq_midi_event 41025 1 snd_seq_oss snd_seq 87777 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi_event snd_seq_device 41557 3 snd_seq_dummy,snd_seq_oss,snd_seq snd_pcm_oss 77377 0 snd_mixer_oss 49985 1 snd_pcm_oss snd_pcm 116681 2 snd_hda_intel,snd_pcm_oss snd_timer 57161 2 snd_seq,snd_pcm snd_page_alloc 44113 2 snd_hda_intel,snd_pcm snd_hwdep 43721 1 snd_hda_intel i2c_i801 41813 0 snd 100201 11 snd_hda_intel,snd_seq_oss,snd_seq,snd_seq_device,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer,snd_hwdep shpchp 70893 0 i2c_core 56641 2 i2c_ec,i2c_i801 e1000e 161441 0 soundcore 41825 1 snd serio_raw 40517 0 pcspkr 36289 0 dm_raid45 99657 0 dm_message 36289 1 dm_raid45 dm_region_hash 46145 1 dm_raid45 dm_mem_cache 38977 1 dm_raid45 dm_snapshot 52233 0 dm_zero 35265 0 dm_mirror 54737 0 dm_log 44993 3 dm_raid45,dm_region_hash,dm_mirror dm_mod 101521 13 dm_multipath,dm_raid45,dm_snapshot,dm_zero,dm_mirror,dm_log ata_piix 56901 2 libata 209489 1 ata_piix sd_mod 56513 3 scsi_mod 196953 12 be2iscsi,ib_iser,iscsi_tcp,bnx2i,cxgb3i,libiscsi2,scsi_transport_iscsi2,scsi_dh,sr_mod,sg,libata,sd_mod ext3 168913 2 jbd 94769 1 ext3 uhci_hcd 57561 0 ohci_hcd 56309 0 ehci_hcd 66125 0 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Don''t you get a shell when it tells you there is an error, where you can try to load the kernel modules by hand and/or test the LVM functionality?

Re: [Xen-users] Volume Group "VolGroup00" not found
"mkinitrd -f --with=lvm2 [...] " doesn''t really work. Running this command, I get an error saying that "No module lvm2 found for kernel 2.6.18.8-xen, aborting.". Is there any kernel config that I have to set to have this module included? Also, when the error occurs during boot, it just restarts; I don''t get any shell.

I''ve tested live migration in the past with RHEL5 and it worked fine back then. Also, the actual Xen version in RHEL/Centos5.5 is 3.1.2 + redhat-specific patches (see "xm info"). Don''t be fooled by rpm version number.> Am I still missing some drivers?Easiest way would be: - use Centos default kernel-xen and see if it works (with your own self-compiled xen, or Xen 3.4.3 from http://www.gitco.de/repo/) - use your own kernel, but use Centos'' kernel-xen config as starting point (/boot/config-*) -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
