[CentOS-virt] Report on Xen-4.6rc2 from virt7-xen-46-candidate

2015-09-08 Thread T.Weyergraf
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@xencen7ws ~]# systemctl status

2016-04-10 Thread T.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.

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
