As mentioned yesterday, Xen 4.6 packages are now available for testing. These also include an update to libvirt 1.3.0, in line with what's available for CentOS 7. Please test, particularly the upgrade if you can, and report any problems here.
To upgrade:
yum update --enablerepo=centos-virt-xen-testing
To install from scratch:
* Install centos-release-xen from centos-extras
yum install centos-release-xen
* Update to get the new kernel:
yum update
* Install the Xen packages from the centos-virt-xen-testing repo:
yum install --enablerepo=centos-virt-xen-testing xen
Keep in mind that there is still a bug in the upstream CentOS new-kernel script which for some people consistently fails to add an "initird" line to the Xen boot stanza. Check /boot/grub/grub.conf; the Xen stanza should look something like this:
title CentOS (3.18.21-17.el6.x86_64) root (hd0,0) kernel /xen.gz dom0_mem=1024M,max:1024M cpuinfo com1=115200,8n1 console=com1,tty loglvl=all guest_loglvl=all module /vmlinuz-3.18.21-17.el6.x86_64 ro root=/dev/mapper/VolGroup-lv_root rd_NO_LUKS LANG=en_US.UTF-8 rd_NO_MD rd_LVM_LV=VolGroup/lv_swap SYSFONT=latarcyrheb-sun16 crashkernel=auto rd_LVM_LV=VolGroup/lv_root KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM rhgb quiet module /initramfs-3.18.21-17.el6.x86_64.img
