XSAs 134, 135, and 136
by George Dunlap 10 Jun '15

10 Jun '15

Just to let people know what's going on: The embargo for XSA-135 lifted today at 1400 UTC. The embargoes for XSAs 134 and 136 lift tomorrow at 1200 UTC. XSA-135 only affects guests which have been assigned a PCNET emulated NIC, which is not the default; as such, it doesn't seem terribly urgent to push the fix today. So rather than push one fix today and another tomorrow, our plan is just to do a single update with all the XSAs tomorrow once the embago lifts. -George

by George Dunlap 09 Jun '15

09 Jun '15

I pushed a draft of a new centos-release-xen rpm repo here: https://github.com/gwd/centos-release-xen The source of this works for both C6 and C7. There's already a C7 package in virt7-xen-44-candidate, and there should be a C6 build in virt6-testing soon. This is to Johnny in particular, but any feedback is welcome. -George

/var/lib/xenstored & Xen4CentOS
by Sarah Newman 04 Jun '15

04 Jun '15

By default, /var/lib/xenstored is mounted tmpfs in centos 5 but this doesn't appear to be true for Xen4CentOS. This can cause performance issues as mentioned in https://bugzilla.redhat.com/show_bug.cgi?id=446089 I'm not sure if this should be part of xencommons, but if not, adding a tmpfs mount should probably be documented on the quick start wiki page. Thanks, Sarah
