No pcifront in F10?
by Jim Lutz 25 Oct '10

25 Oct '10

I have a virtual machine landscape consisting of a CentOS 5.3 Dom0 with Xen 3.1.2, some PV CentOS DomU's with PCI passthrough (same versions), and I'm trying to implement a F10 DomU with PCI passthrough. I set everything up for the passthrough, and the F10 guest can't see any of the devices with lspci. If I boot a CentOS PV machine with the same PCI passthrough configuration, the devices show up with lspci. I've seen some posts in various places about this issue, but no solutions. How do I implement this?

Dom0 kernels
by M A Young 13 Mar '10

13 Mar '10

I have built a new set of kernel packages based on fedora rawhide kernels and the xen/dom0/hackery branch of Jeremy's git repository ( http://git.kernel.org/?p=linux/kernel/git/jeremy/xen.git;a=summary ). This batch (kernel-2.6.29-0.114.2.6.rc6.fc11) is available via the koji build system at http://koji.fedoraproject.org/koji/taskinfo?taskID=1149500 These are really for development and debugging purposes only, as I am still having problems getting them to boot, but others have reported more success at getting kernels based on this git repository working, so you might be lucky. Note to install these packages on Fedora 10 you will need to have rpm-4.6.0-1.fc10 installed (currently in updates-testing but it should be available in updates soon) because of the change to SHA-256 file digest hashing in recent Fedora 11 builds.

Fedora 12 (rawhide) Xen domU works now, minor console keymap issue?
by Pasi Kärkkäinen 08 Nov '09

08 Nov '09

Hello, Kernel 2.6.31-0.203.rc8.git2.fc12.i686.PAE for F12/rawhide domU seems to work now on my F11 host with xen-3.4.1-3 + libvirt from F11 updates-testing + 2.6.31-rc6 pv_ops dom0 kernel. There's a minor issue with domU vfb graphical console keymap though.. The F11 host has 'fi' (Finnish) keymap, and the F12 domU/guest is also installed with 'fi' keymap. All the 'special' keys on the graphical console (virt-viewer) are broken.. I don't really know what the resulting keymap is, but it's pretty weird. Not english, not finnish, not anything I know of.. List of the important characters that are broken: * / - _ | ? \ ( ) Either you can't make them at all, or you have to press totally wrong buttons to get them.. so the console is really painful or impossible to use. Any ideas how to debug this? Or is non-US even supposed to work? Thanks! -- Pasi

RE: [Xen-devel] Virt-manager issue resolved

Could you summarize the procedure? I am trying to run virt-manager on Fedora 11 with Xen-3.5-unstable and Jeremy's Dom0 (git://git.kernel.org/pub/scm/linux/kernel/git/Jeremy/xen.git). I am wondering what option should be good on make on xen-3.5-unstable. I did Make xen tools Make install-xen install-tools What else I need do?

Host is a f8 dom0 running xen-3.1.2-5.fc8 and kernel 2.6.21.7-5.fc8xen.x86_64. I updated a f10 guest domU to the latest kernel update 2.6.27.30-170.2.82.fc10.x86_64 and rebooted it without problem. I updated a f11 domU to kernel-2.6.30.5-43.fc11.x86_64 and the guest crashes after grub. Cracking open the image and setting grub back to kernel-2.6.29.6-217.2.16.fc11.x86_64 got me up and running. xm dmesg shows (XEN) traps.c:405:d117 Unhandled general protection fault fault/trap [#13] in domain 117 on VCPU 0 [ec=0000] (XEN) domain_crash_sync called from entry.S (XEN) Domain 117 (vcpu#0) crashed on cpu#3: (XEN) ----[ Xen-3.1.4 x86_64 debug=n Not tainted ]---- (XEN) CPU: 3 (XEN) RIP: e033:[<ffffffff813cda87>] (XEN) RFLAGS: 0000000000000282 CONTEXT: guest (XEN) rax: 000000008000c068 rbx: 000000000000c000 rcx: 0000000000000068 (XEN) rdx: 0000000000000cf8 rsi: 0000000000000018 rdi: 0000000000000000 (XEN) rbp: ffffffff8172de48 rsp: ffffffff8172dde0 r8: 0000000000000068 (XEN) r9: ffffffff8172de60 r10: ffffffff8172de68 r11: 00000000ffffffff (XEN) r12: ffffffff81697500 r13: ffffffff8172df78 r14: ffffffffffffffff (XEN) r15: 0000000000000000 cr0: 000000008005003b cr4: 00000000000006f0 (XEN) cr3: 00000002f53fe000 cr2: 0000000000000000 (XEN) ds: 0000 es: 0000 fs: 0000 gs: 0000 ss: e02b cs: e033 (XEN) Guest stack trace from rsp=ffffffff8172dde0: (XEN) 0000000000000068 00000000ffffffff 0000000000000000 ffffffff813cda87 (XEN) 000000010000e030 0000000000010082 ffffffff8172de28 000000000000e02b (XEN) ffffffff813cda4d ffffffff8172de88 965f5967f03da9c3 ffffffff8100a7ed (XEN) ffffffff81722b80 ffffffff8172de88 ffffffff8148f7c1 00020f5103000800 (XEN) 0000000000000000 0000302800000000 965f5967f03da9c3 ffffffffffffffff (XEN) 0000000000000018 ffffffff8172dea8 ffffffff81760bc2 ffffffff8179ca10 (XEN) 0000000000000000 ffffffff8172df58 ffffffff8175ce66 0000000000000000 (XEN) 965f5967f03da9c3 ffffffff8172dee8 ffffffff8179ca10 0000000000000000 (XEN) 0000000000000000 ffffffffffffffff 0000000000000000 ffffffff8172df58 (XEN) ffffffff81495adb ffffffff00000010 ffffffff8172df68 ffffffff8172df28 (XEN) 965f5967f03da9c3 00000000a1b58930 ffffffff8179ca10 0000000000000000 (XEN) 0000000000000000 ffffffffffffffff 0000000000000000 ffffffff8172dfa8 (XEN) ffffffff81757d0b ffffffff8172dfa8 965f5967f03da9c3 ffffffff82226000 (XEN) 0000000000000000 00000000019d0f60 0000000000000000 0000000000000000 (XEN) 0000000000000000 ffffffff8172dfd8 ffffffff817572d0 0000000000000018 (XEN) 0000000000000000 0000000000000000 ffffffff82226000 ffffffff8172dff8 (XEN) ffffffff8175b4e0 0000000000000000 0000000000000000 0000000000000000 (XEN) ffffffff82123000 ffffffff82124000 ffffffff82125000 ffffffff82126000 (XEN) ffffffff82127000 ffffffff82128000 ffffffff82129000 ffffffff8212a000 (XEN) ffffffff8212b000 ffffffff8212c000 ffffffff8212d000 ffffffff8212e000 (XEN) traps.c:405:d118 Unhandled general protection fault fault/trap [#13] in domain 118 on VCPU 0 [ec=0000] (XEN) domain_crash_sync called from entry.S

Dom0 Support in fc11.x86_64
by Stephen Johnston 29 Oct '09

29 Oct '09

Hi All I have been lurking albeit lazily recently so please excuse me if this is a stupid question. Does fc11.x86_64 support a Dom0 yet? Im quite happy to reinstall with a xen kernel if it does otherwise I am consider Solaris.

virt-manager using iscsi
by Jon R. 19 Oct '09

19 Oct '09

Hello, Stats: FC11 xen-3.4.1 virt-manager 0.7.0 2.6.31-rc6 I have setup a domU to serve up iscsi disks that are really LVs on the host. I have configured ied.conf to use these LVs as iscsi targets. I have an .iso loopback mounted and offered up on my webserver for HTTP installs. When I try to create a new domU I have to uncheck 'Enable storage for this virtual machine' and then specify 'Add Target' during the disk portion of the install. It finds the disk and labels it as sda but the "What Drive Would You Like To Boot This Installation From?" is grayed out. Unless you choose 'Custom Partition' you cannot move on. I choose 'Custom Partition' and create my partitions as simple as possible. /boot 200MB swap 512MB / Rest of drive I hit 'Next' and the dialog box 'Creating File System On /dev/sda1'. I watch the target server on port 3260 with tcpdump. I see traffic passing back and forth between the domU's, the one acting as the target and the one being installed with virt-manager. The dialog box just stays on the console and the traffic eventually comes to a complete stop. I am getting nothing useful in the logs on either dom0 or domU as to why it just dies. Has anybody ran into this before? Is this never going to work because of my setup? Can iSCSI be the /boot? How do you specify iscsi using virt-install? Maybe I could get a little more output that way. Any ideas appreciated, Jon
