Hi all, Looking to move from VMware to Xen4CentOS. We currently run Centos7 as our servers main distort. All the documentation I?ve found on the Xen4CentOS only refers to Centos6. Do any of you know if it currently or is being developed to work with Centos7? thanks in advance

All, I have compiled an experimental 3.18.12 kernel from the 3.18 LTS kernel branch from kernel.org for the Xen4Centos 6 tree. http://people.centos.org/hughesjr/xen-kernel/x86_64/ This should be considered extremely experimental at this point and is unsigned. I have tested it on 2 generic servers and it worked fine on both of those with sata and gigabit ethernet. Please test this and provide

Do we want to move the Xen4CentOS kernel to new LTS 3.10.x from the current 3.4.x Kernel? If so, can we start testing the that kernel build? Is someone from Xen.org working on porting the xen specific patches that are required in the 3.10.x kernel from the ones we have in the 3.4.x tree in Xen4CentOS? The only one I know we need is the blktap module. I have created a new spec that builds a

I think this may have been asked before, but what would it take to get debuginfo packages built for the Xen4CentOS kernels? If it's just a patch for kernel.spec file that nobody has gotten around to, what is the best starting place for making that patch? Thanks, Sarah

Hello, It seems currently when you "yum update" CentOS 6.6 Xen host you end up getting python-virtinst from c6 base repo: python-virtinst-0.600.0-24.el6.noarch and not from Xen4CentOS repo, because the version there is "older": 0.600.0-19. .. which means the centos/xen-specific patch in python-virtinst is "lost". (default to tap2 instead of tap1, to make blktap2

By default, /var/lib/xenstored is mounted tmpfs in centos 5 but this doesn't appear to be true for Xen4CentOS. This can cause performance issues as mentioned in https://bugzilla.redhat.com/show_bug.cgi?id=446089 I'm not sure if this should be part of xencommons, but if not, adding a tmpfs mount should probably be documented on the quick start wiki page. Thanks, Sarah

I installed CentOS6 with the xen4centos set of packages; then I tried to install KVM (for performance comparison), I got the following error in YUM: --> Processing Dependency: /usr/share/gpxe/e1000-0x100e.rom for package: 2:qemu-kvm-0.12.1.2-2.415.el6_5.4.x86_64 Package gpxe-roms-qemu is obsoleted by ipxe-roms-qemu, but obsoleting package does not provide for requirements I manually

Folks near New York City may want to come hear Johnny Hughes talk about Xen4CentOS and the Virtualization SIG next Monday at the Xen Project User Summit.

It looks like no XSA-142 patch, which is "libxl fails to honour readonly flag on disks with qemu-xen" has been applied to Xen4CentOS. I assume this was on purpose? If not, I can have someone try adding the original patch from http://xenbits.xen.org/xsa/advisory-142.html and some variant of the commit from ef6cb76026628e26e3d1ae53c50ccde1c3c78b1b

Hi, Trying to get a handle on the 'not included' aspects of Xen4CentOS. Anyone care to share their experiences with xm vs virtinstall vs virt-manage. Currently I'm running one xm create config to launch a CentOS cd based kickstart install, then I use a second xm create config to run the created systems. Thoughts on pvgrub and running unmodified kernels from within the pv guest. Is

We need a way to do two things to /usr/bin/grub-bootxen.sh in Xen4CentOS. 1. Automate running it if xen (the package) and the xen kernel are installed. But only if the user WANTS to run it. 2. Allow users to automatically modify the variables passed into the xen.gz line (that is, more or less memory, add console settings, etc.) If you look at the current script,

KB and I were looking at repositories to import into git.centos.org recently, and we found the e1000e package -- a rebuild of the Intel e1000 driver for the x4c kernel. Does anyone know if this externally-build module is still necesssary for Linux 3.10? Or for Linux 3.14, which we're planning on moving to at some point in the near future? -George

Hi folks, we (the company i am working for) are running several dozens of virtualisation servers using CentOS 6 + Xen4CentOS as the virtualisation infrastructure. With the latest versions of all packages installed [1], we see failures in live-migration of stock-CentOS6 HVM guests, leaving a "Domain-unnamed" on the source host, while the migrated guest runs fine on the target host.
