Hello, I was wondering if there is a way to execute commands from dom0 into domU without loging into domU with ssh. thanks

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 to rawhide?
by W. Michael Petullo 23 Aug '10

23 Aug '10

I have been using Michael Young's Xen Dom0 kernels. With kernel 2.6.34 in Rawhide, what is keeping Xen 4.0 and a DomU kernel from being pushed to Rawhide? My understanding was that kernel 2.6.33 would provide the pvops features required to make a Dom0 kernel palatable to Fedora. Did this feature not make this release? http://fedoraproject.org/wiki/Features/XenPvopsDom0 has not been updated in a while, but I suspect that a Xen Dom0 kernel will not be in Fedora 13. -- Mike :wq

dom0 kernel
by M A Young 22 Jun '10

22 Jun '10

Another dom0 kernel is available at http://koji.fedoraproject.org/koji/taskinfo?taskID=2071068 or from the repository http://fedorapeople.org/~myoung/dom0/ . This kernel requires xen 3.4.3 or xen 4.0.0 and a source rpm for xen-4.0.0-rc7 is at http://fedorapeople.org/~myoung/dom0/src/xen-4.0.0-0.5.rc7.fc12.src.rpm This kernel is the first that boots for me on i686 for a long time. It also switches from initrd to initramfs boot partitions which should make it easier to use on Fedora 13. Michael Young

Move from Fedora 8 dom0s to F12/F13 dom0s with Xen 4.0.x questions
by fcxen user 22 May '10

22 May '10

I would like to try to move some dom0s from Fedora 8 to Fedora 12/13/Xen 4.0, but I had a few questions. Some of these are probably repeats so I apologize in advance. * I use "virsh define" to create the VM configurations using virsh xml, and I assume that virsh/libvirtd won't work on a recent 2.6.32/33/3x kernel and Xen 4.0.0 Is there a way to extract the xm style configuration values from the running VMs? Or a file somewhere so I can pull out/copy the VM configs for use on the new machine or is there another way to do that? It has been since about Fedora Core 5 that I used the xm style configs so I don't have that in my head like many on this list do. * I am using plain disk files for the storage for each VM, I understand that Xen 4.0 has the ability to use these now with the correct kernel. Is that the case? Would I be able to use my current (F10-F12) VMs as is? * Although Pasi, Michael, Dale and others have been very generous with their information, testing and development, I am not completely clear on all the steps required to get a working F12/F13/ Xen 4.0.X dom0 with 2.6.32/33/3x kernel starting from a base F12/F13 system install. If someone can point out where to find different parts I would be grateful and would be willing to consolidate them into a single blob if that doesn't already exist. I looked at some of the wiki some on the xen wiki but I get a bit of choice overload from those pages - you can use this kernel or that kernel or... * If this were to work, would I see a performance increase or (hopefully not) decrease for vanilla F10-F12 domUs (apache, etc) on the same hardware going from Xen 3.1.4 on F8 to Xen 4.0.x on F12/F13 on Intel 5400/5500 based servers? Thanks for any help. One of the other reasons I want to upgrade is because I can no longer add VMs with virt-install command line. I constantly get: libvir: Xen Daemon error : GET operation failed: xend_get: error from xen daemon: virDomainLookupByID() failed GET operation failed: xend_get: error from xen daemon: Even after upgrading to libvirtd 0.4.6-1.fc8 and even immediately after rebooting the dom0 - which seemed to be a workaround for others that I read about having this problem. I realize this is not the libvirtd list but a couple of the replies to this problem that I have seen are along the lines of "it is not a libvirt problem". And If it is not too painful to get the F12/F13 dom0s working with my old VMs, I hope to just forget all about this :)

Yeah, I think it misses the boat. Maybe 3.4.4 if there is some developer interest in cherry-picking the patches, and sufficient testing effort. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel(a)lists.xensource.com http://lists.xensource.com/xen-devel

Fedora 13 rc as Xen PV guest test report
by Pasi Kärkkäinen 14 May '10

14 May '10

Hello, I just tried installing Fedora 13 release candidate as Xen PV guests/domUs: - F13 rc 32bit PAE Xen PV guest (kernel 2.6.33.3-85.fc13.i686.PAE) - F13 rc 64bit Xen PV guest (kernel 2.6.33.3-85.fc13.x86_64) Xen dom0 for these tests was RHEL 5.5 x86_64. I installed F13 guests using virt-manager and http fedora mirror. Both installed OK, no problems found. Absolute mouse pointer worked OK on the graphical console. RHEL 5.5 has pygrub support for ext4, so having F13 guest /boot on ext4 (the default for F13) is not a problem anymore. I also tested save/restore functionality: - F13 64bit guest with 1 and 4 vcpus: save/restore OK. - F13 32bit PAE guest with 1 and 4 vcpus: save/restore OK. -- Pasi
