** Description changed: Upgrade of a kvm based virtio vm from 10.04 to 12.04 (beta). Note: slightly broken "do-release-upgrade -d" as some library keep causing screen to crash. apt-get update and apt-get dist-upgrade completed the upgrade. Seems the Linux kernel server package for 10.04 - which is 2.6.32-39-server - defaults to upgrading to 3.2.0-18-GENERIC. I think - have not confirmed - that this kernel does not contain drivers for virtio blockio. So boot fails with "Unable to mount root fs on unknown-block" boot errors. I was able to boot into the 10.04 kernel, and after some investigation replace the -GENERIC kernel with the -VIRTUAL kernel. The system now boots correctly. nic@shell:~$ lsb_release -rd Description: Ubuntu precise (development branch) Release: 12.04 nic@shell:~$ cat /proc/version_signature Ubuntu 3.2.0-18.28-virtual 3.2.9 nic@shell:~$ sudo lspci -vnvn | grep Virt 00:03.0 Ethernet controller [0200]: Red Hat, Inc Virtio network device [1af4:1000] 00:04.0 Ethernet controller [0200]: Red Hat, Inc Virtio network device [1af4:1000] 00:05.0 SCSI storage controller [0100]: Red Hat, Inc Virtio block device [1af4:1001] + --- + AlsaDevices: + total 0 + crw-rw---T 1 root audio 116, 1 Mar 9 17:25 seq + crw-rw---T 1 root audio 116, 33 Mar 9 17:25 timer + AplayDevices: Error: [Errno 2] No such file or directory + ApportVersion: 1.94.1-0ubuntu1 + Architecture: amd64 + ArecordDevices: Error: [Errno 2] No such file or directory + AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: + CRDA: Error: command ['iw', 'reg', 'get'] failed with exit code 1: nl80211 not found. + CurrentDmesg: [11424.931185] sched: RT throttling activated + DistroRelease: Ubuntu 12.04 + HibernationDevice: RESUME=/dev/mapper/shell-swap_1 + IwConfig: + lo no wireless extensions. + + eth1 no wireless extensions. + + eth0 no wireless extensions. + Lsusb: Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub + MachineType: Bochs Bochs + Package: linux (not installed) + PciMultimedia: + + ProcEnviron: + TERM=xterm + LANG=en_NZ.UTF-8 + SHELL=/bin/bash + ProcFB: + + ProcKernelCmdLine: root=/dev/mapper/hostname-root ro quiet splash + ProcVersionSignature: Ubuntu 3.2.0-18.28-virtual 3.2.9 + RelatedPackageVersions: + linux-restricted-modules-3.2.0-18-virtual N/A + linux-backports-modules-3.2.0-18-virtual N/A + linux-firmware 1.71 + RfKill: Error: [Errno 2] No such file or directory + Tags: precise + Uname: Linux 3.2.0-18-virtual x86_64 + UpgradeStatus: Upgraded to precise on 2012-03-08 (0 days ago) + UserGroups: adm admin cdrom dialout lpadmin plugdev sambashare + dmi.bios.date: 01/01/2007 + dmi.bios.vendor: Bochs + dmi.bios.version: Bochs + dmi.chassis.type: 1 + dmi.chassis.vendor: Bochs + dmi.modalias: dmi:bvnBochs:bvrBochs:bd01/01/2007:svnBochs:pnBochs:pvr:cvnBochs:ct1:cvr: + dmi.product.name: Bochs + dmi.sys.vendor: Bochs ** Attachment added: "AcpiTables.txt" https://bugs.launchpad.net/bugs/950529/+attachment/2838812/+files/AcpiTables.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/950529 Title: 10.04 kvm vm upgrade to 12.04 - boot fail on 3.2.0-18-generic, but will boot 2.6.32-39-server To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/950529/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
