Hello, Now that the Xen 4.4.1 rpms + libvirt 1.2.10 rpms for CentOS 6 seem to be in good shape it would be a good time to start experimenting with el7 builds aswell. I think it's best to start with the same set of packages we have for el6, and just do the minimum required changes to get them working on centos7. That probably means fixing some dependencies in the spec file, and some changes

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

At long last, I've got some beta CentOS 6 4.4.1 packages up on the CBS. Major updates include: * Update to Xen 4.4.1. Also includes all XSAs through 114 * Update to latest blktap 2.5 * Updated libvirt packages (1.2.10), which work well with libxl To use, add the following to a file in /etc/yum.repos.d: [virt-testing] name=CentOS-$releasever - virt-testing

Hello, I just upgraded some of my el6xen boxes to latest CentOS 6.7, Xen 4.4.3 and dom0 3.18.17 rpms, and noticed these new problems: 1) virt-manager fails to start with an error: "D-Bus library appears to be incorrectly set up; failed to read machine uuid: Failed to open "/var/lib/dbus/machine-id": No such file or directory" And indeed.. there was no such file.

Good test, non-buffered dom0 dd write speed is similar with tap2. I'll likely stay with the QEMU backend. Are there any best practises regarding security, at least if QEMU can operate under non-root account?
