by Kevin Stange 14 Sep '17

Hi all, Sorry for running a bit behind on security patch releases for the Xen-44 branch. As of yesterday, package version 4.4.4-28 was released for testing, which includes all relevant XSA patches through XSA-235 here: https://buildlogs.centos.org/centos/6/virt/x86_64/xen-44/ Please test and provide feedback if possible so we can get this package moved to release fairly soon. Currently in the release repo is 4.4.4-27 as of last week, which contains all relevant patches through XSA-230. -- Kevin Stange Chief Technology Officer Steadfast | Managed Infrastructure, Datacenter and Cloud Services 800 S Wells, Suite 190 | Chicago, IL 60607 312.602.2689 X203 | Fax: 312.602.2688 kevin(a)steadfast.net | www.steadfast.net

change network settings of VM depending on logged in user(s)?
by hw 08 Sep '17

08 Sep '17

Hi, is there a way to disable internet access for a windoze 7 VM depending on which user(s) is/are logged in? It seems windoze 7 doesn´t really support this, especially when you want to disable internet access for the whole machine, so I´m wondering if there is a way to do this when the machine is a KVM-VM running on Centos. The whole VM should only have internet access when a particular user logs in, and preferably for only this particular user.

by Johan Guldmyr 08 Sep '17

08 Sep '17

Hello! http://mirror.centos.org/centos/7/virt/x86_64/kvm-common Latest is now qemu-kvm-ev-2.6.0-28.el7.10.1.x86_64.rpm while http://ftp.redhat.com/redhat/linux/enterprise/7Server/en/RHEV/SRPMS/ has qemu-kvm-rhev-2.6.0-28.el7_3.12.src.rpm A few questions: A) Does kvm-common have RPM builds from RHEV's SRPMS? B) Is the plan to keep kvm-common up to date with RHEV? // Johan Guldmyr

Major stability problems with xen 4.6.6
by Nathan March 29 Aug '17

29 Aug '17

Hi, I'm seeing numerous crashes on the xen 4.6.6-1 / 4.6.6-2 releases, on both the 4.9.34-29 and 4.9.39-29 kernels. I've attached a txt with two different servers outputs. Xen-028: This crashed this morning while running 4.6.6-1 and 4.9.39-29 Xen-001: This crashed shortly after being upgraded to 4.6.6-2 and 4.9.34-29 Both are on different hardware platforms, and have had a long history of being stable until these upgrades. It sounds potentially related to https://kernel.googlesource.com/pub/scm/linux/kernel/git/tiwai/sound-unstabl e/+/9ce119f318ba1a07c29149301f1544b6c4bea52a%5E%21/ but I've confirmed this patch is in the above kernels. Any suggestions / thoughts? Cheers, Nathan
