...of modern Xen4CentOS setup to replace our aged setup in our infrastructure, i thought i'd rather settle with something as new as possible to avoid running into "not supported anymore soon" issues. Check hypervisor support matrix on frontpage https://xenproject.org/ Regards Thomas Weyergraf

Hi all, i just stumbled over a strange performance issue with my Xen setup. I use centos-virt Xen since a long time on my workstation and usually never check performance. However, yesterday I booted into the 3.18.25-19 Dom0 kernel *without* Xen and found the system noticably more responsive. That triggered me into running a simple kernel compile benchmark and compare the results:

...ed to build our own Xen 4.2.2 based on a git repo, published by Karanbir Singh. We had several issues with that version, but never observed a "Domain-unnamed". Any idea how to resolve this issue would be highly appreciated, as working live-migration is crucial to us. Regards, Thomas Weyergraf Some notes on our config: 1. We still use xm/xend for various reasons ---- 2. Our grub-config for the virtx-hosts is as follows: ---- default=0 timeout=5 #splashimage=(hd0,0)/grub/splash.xpm.gz #hiddenmenu title CentOS (xen-4.2.5-37.el6.gz vmlinuz-3.10.56-11.el6.centos.alt.x86_64) root (...

...sing pv-ops xen/stable 2.6.32 series? If applicable, I''d be more than happy to provide assistance to move forward pvscsi. Maybe, as a start, provide a short, practical howto about what I did above to get pvscsi working and reference it by the Xen PVSCSI wiki page [3]?

Hi folks As mentioned in the subject, kernel-3.18.12-11 is missing firmware files required to run Broadcom/Qlogic network cards, driven by bnx2x driver. While in the source-rpm, there is a bnx2/bnx2x firmware tgz being applied during the rpm build, along with a patch adding these firmware files to firmware/Makefile, neither the tgz nor the patch contain the required firmware files. In 3.18,

Hi I gave the new Xen-4.6rc2 a spin on a CentOS 7 virtualisation guest (nested-xen). I haven't yet started testing guests, but rather looked at the install itself. One issue, I found, was with xenstored.service and the corresponding unit-file: [root at xencen7ws ~]# systemctl status xenstored xenstored.service - The Xen xenstore Loaded: loaded

Hi So far, I did some preliminary testing using nested virt: host(L0): Fedora 25, kernel-4.9.11-200, kvm+qemu Guest(L1): CentOS 7 Xen-4.6.3-7, kernel-4.9.11-22 So far, at least the L1 setup had no issues. I'll need to pull L1 guest-storage from backup to test some L2 guests. Likewise, I try to allocate two blades at work for tests on real metal. Our standard-tests include starting

Greeting, We are about to update the centos-release-xen package to point to Xen 4.8 rather than 4.6. I'll push the update next week. As a reminder, you can "pin" your installation to Xen 4.6 by installing centos-release-xen-46 and then removing centos-release-xen. And for the more adventurous, that update will come with a new package centos-release-xen-410 to install Xen 4.10.

At long last, I'd like to announce beta packages for CentOS 7, available from the community build system. Start by installing the centos-release-xen: rpm -ivh http://cbs.centos.org/repos/virt7-xen-44-testing/x86_64/os/Packages/centos-release-xen-7-3.el7.x86_64.rpm This will set up yum repositories for both the eventual release repositories (enabled by default), and the community build

Hi Thomas, This may be old news at this point, but I had 100% identical behavior to yours when I tried virtx7-44-testing. After looking around a bit I tried "virtx7-44-candidate", in a sibling directory to virtx7-44-testing. It has a more recent date, so I tried with that and it works fine. It resolves the issues listed in your email from 7/7/2015. I am now looking for a
