Any of you guys ever seen an issue with Xen 4.4 were xm cannot create a guest because of what looks like an issue allocating memory even though xm info shows like 5x the amount of free memory needed? We are still unfortunately still using xm... it's on my list, i know.. We've had this happen on a couple hosts now. Only way to resolve seams to be rebooting the host. I'm going to

Hi Guys Apologies in advance for the noise. I am interested in setting up my OWN mirrorlist like http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock where it pulls a few local mirrors, but mine would be statically set with 3 or 4 different location URL's Basically my plan here is, if the closest mirror I operate cannot be reached, it will try another

Problems start before any of the kaiser code executes, though it could still be related to CONFIG_KAISER since that has effects beyond kaiser.c. --- (early) Initializing cgroup subsys cpuset (early) Initializing cgroup subsys cpu (early) Linux version 2.6.32-696.18.7.el6.x86_64 (mockbuild at c1bl.rdu2.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-18) (GCC) ) #1 SMP Thu Jan 4 17:31:22 UTC
