I tried many ISO's and the systems that worked before I did a dist upgrade failed to boot also
I just tried it with 2 cpu's and 2GB of ram and it still failed. I do not get to a point where I can get dmesg output but I have included a screenshot I have reproduced this issue on a Dell R710, 2950 and R610. I installed with the 11.04 Server ISO image. Re-installing 10.10 server allowed the guests to boot as did dropping the vcpu number down to 1 Here are the ISO images I was using for the guests. root@usmirror001:/export/isos/Operating_Systems/Linux# isoinfo -d -i CentOS-5.5-i386-bin-DVD.iso CD-ROM is in ISO 9660 format System id: LINUX Volume id: CentOS_5.5_Final Volume set id: Publisher id: CentOS Project Data preparer id: CentOS Application id: CentOS_5.5_Final Copyright File id: Abstract File id: Bibliographic File id: Volume set size is: 1 Volume set sequence number is: 1 Logical block size is: 2048 Volume size is: 2043515 El Torito VD version 1 found, boot catalog is in sector 406 Joliet with UCS level 3 found Rock Ridge signatures version 1 found Eltorito validation header: Hid 1 Arch 0 (x86) ID 'CentOS Project' Key 55 AA Eltorito defaultboot header: Bootid 88 (bootable) Boot media 0 (No Emulation Boot) Load segment 0 Sys type 0 Nsect 4 Bootoff 197 407 root@usmirror001:/export/isos/Operating_Systems/Linux# isoinfo -d -i CentOS-5.6-i386-LiveCD.iso CD-ROM is in ISO 9660 format System id: LINUX Volume id: CentOS-5.6-i386-LiveCD Volume set id: Publisher id: Data preparer id: Application id: MKISOFS ISO 9660/HFS FILESYSTEM BUILDER & CDRECORD CD-R/DVD CREATOR (C) 1993 E.YOUNGDALE (C) 1997 J.PEARSON/J.SCHILLING Copyright File id: Abstract File id: Bibliographic File id: Volume set size is: 1 Volume set sequence number is: 1 Logical block size is: 2048 Volume size is: 354800 El Torito VD version 1 found, boot catalog is in sector 36 Joliet with UCS level 3 found Rock Ridge signatures version 1 found Eltorito validation header: Hid 1 Arch 0 (x86) ID '' Key 55 AA Eltorito defaultboot header: Bootid 88 (bootable) Boot media 0 (No Emulation Boot) Load segment 0 Sys type 0 Nsect 4 Bootoff 25 37 ** Attachment added: "Screen capture of where it gets stuck" https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/795717/+attachment/2179933/+files/rhel3crash.png -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/795717 Title: 32bit rhel and centos 5.(5|6) hangs on boot on natty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/795717/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
