2.6.32 dom0 kernel
by M A Young 18 May '11

18 May '11

I have built a new 2.6.32 kernel, based on my Fedora 12 kernels, but with updates to the latest 2.6.32 kernel patch (2.6.32.34 with the extra patch to make it equivalent to 2.6.32.35) and latest xen next-2.6.32 patch. It was built on Fedora 13. It is available (temporarily) from koji at http://koji.fedoraproject.org/koji/taskinfo?taskID=2940510 and from my repository http://repos.fedorapeople.org/repos/myoung/dom0-kernel/ Michael Young

2.6.32.x dom0 kernel
by M A Young 28 Apr '11

28 Apr '11

I have built another 2.6.32.x based kernel (2.6.32.25-172.xendom0.fc12) at http://koji.fedoraproject.org/koji/taskinfo?taskID=2583536 and the repository http://repos.fedorapeople.org/repos/myoung/dom0-kernel/ . This updates the kernel from 2.6.32.25-rc1 to 2.6.32.25 (which may not actually change anything), and uses a later version of xen/stable-2.6.3.32.x which adds a couple of xen fixes. Michael Young

confused about xen caps
by Mike Wright 28 Mar '11

28 Mar '11

Hi all, Using fedora14 and running xen-4.0.1 but when executing "xm info" the following is displayed: xen_caps: xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64. Should I ignore this and assume it is actually xen-4? TIA, Mike Wright

running xen without libvirt, etc
by Mike Wright 27 Mar '11

27 Mar '11

Hi all, Very confused as to which list I should post: xen, fedora, fedora-xen. Apologies if this is the wrong one. Pointer to the most appropriate list is welcome. Current system is f14 with full updates, myoung's kernel 2.6.32.+, booted with xen 4.0.1. Hardware is AMD with svm, lotsa ram. After fighting with the all-in-one GUIs for virtmanager I gave up and tried to recycle my configs from a 2006 box running xen3 (which still purrs) and can't even get past scripts/network-bridge without a hang or no bridges. I'm not asking for help on creating a vm, just on getting dom0 to recognize even one single bridge, even the default one. My feeling is that if I can get that far I can take it from here. Does anybody have a working example of a current xend-config.sxp for a machine running xend with f14? Thanx, Mike Wright

virtinst: do I have virtualization or not?
by Mike Wright 21 Mar '11

21 Mar '11

Hi all, Using f14-x86_64 installed from the LiveCD with myoung's f12-xendom0. It boots both standalone and with xen. /sys/hypervisor is populated. /proc/cpuinfo reports CPU is AMD Phenom II X4 B60 "Black Edition". Virtualization is [ENABLED] in the BIOS. I'm trying to add a virtual machine using Virtual Machine Manager 0.8.5 but when I select *New* I receive the following: "Warning: Host does not appear to support hardware virtualization. Install options may be limited." According to this link (s.b. one line) it does. "http://www.cpu-world.com/CPUs/K10/AMD-Phenom%20II%20X2%20560%20-%20HDZ560WF…". Now according to another webpage the AMD processor must have the flag "svm" to have virtualization. My CPU does NOT have that flag but it does have one called "hypervisor". The question becomes "will this CPU work with Xen?". If it will, does this mean there is a bug in virtinst? Can I ignore the warning? Thanks for any help, Mike Wright

Testing Xen dom0 for Fedora 15
by Tim Flink 19 Mar '11

19 Mar '11

I was wondering about the progress towards dom0 support in F15. The feature page [1] hasn't been updated for a while, so I'm not clear on how close the feature is to completion. Specifically, I am looking to find out what kind of testing has been done or is being done for this new feature. As far as I know, the Fedora QA community is not very aware of xen dom0 support and it isn't a part of the test cases that we have been running. If dom0 support is likely to be complete in time for F15, we would certainly welcome assistance in writing test cases and/or helping out with the upcoming virtualization test day on 2011-04-14 [2]. Thanks, Tim [1] http://fedoraproject.org/wiki/Features/XenPvopsDom0 [2] https://fedoraproject.org/wiki/QA/Fedora_15_test_days

2.6.38-rc6 dom0 kernel
by M A Young 14 Mar '11

Here is another kernel (2.6.38-0.rc6.git0.1.xendom0.fc15) at http://koji.fedoraproject.org/koji/taskinfo?taskID=2861178 . This comes with a warning because for me the dom0 system reboots when a domU guest is shutdown. Michael Young
