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:

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.

Hi I am attempting to setup Xen 4.10 with kernel 4.9.86-30 ( virt7-xen-410-testing, virt7-common-testing ) on CentOS7 After installing everything, the machine was unable to boot and hung in dracut stating it could not find its root device. The testsystem I use is a somewhat aged Dell M915 Blade (Quad opteron 61xx), using an MPT SAS controller for it's SAS boot drives. Stock CentOS 7

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

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.

I gave the virtx7-44-testing packages a spin on a fresh CentOS 7 install (legacy boot, no efi, as there is no xen.efi). However, I was not able to start any HVM or PVHVM guests. Upon

Hi I wonder, if live migration (back and forth) is possible on mixed Haswell (Xeon V3) and Broadwell (Xeon V4) installations. The only notable difference between the two is apparently a working TSX implementation on V4, which got disabled on V3 due to bugs. The rest (VMCS-shadowing, posted interrupts) should not apply to our environment, as we do not run nested-vmx nor device-passthrough on

Hi Thanks for providing updated Packages, they are much appreciated. At work, we are currently running an entire production infrastructure on Xen4CentOS, with quite some success. We are looking into a refresh towards CentOS 7 along with newer Xen and Dom0 Kernel packages. However, even the updated packages are quite old. Xen 4.8 is out of active support since June and will see the end of

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 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

Hi, I am working as a system administrator at an internet platform service provider, and I am currently seeking to re-new our Xen virtualization infrastructure for which I am mostly responsible for. Currently, we run Xen 3.4.2/3.4.3 on RHEL/CentOS 5.x (5.7) as Dom0 with CentOS 5.x pv-guests. Based on my experiments, I am currently looking into Xen 4.1.2 on RHEL/CentOS 6.x (6.2), with a
