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 update the host to latest Xen 4.4 now hoping this is a old bug. Here's from xen logs [2016-06-22 09:13:50 1958] DEBUG (XendDomainInfo:105) XendDomainInfo.create(['vm', ['name', 'xxx'], ['memory', 2048], ['on_xend_start', 'ignore'], ['on_xend_stop', 'ignore'], ['vcpus', 2], ['oos', 1], ['image', ['linux', ['kernel', '/kernels/vmlinux-2.6.18.8-4'], ['videoram', 4], ['args', 'root=/dev/xvda ro xencons=tty console=tty1 '], ['tsc_mode', 0], ['nomigrate', 0]]], ['s3_integrity', 1], ['device', ['vbd', ['uname', 'phy:vg/fs_6818'], ['dev', 'xvda'], ['mode', 'w']]], ['device', ['vbd', ['uname', 'phy:vg/fs_6819'], ['dev', 'xvdb'], ['mode', 'w']]], ['device', ['vif', ['rate', '40mb/s'], ['mac', 'FE:FD:48:01:F1:E7']]]]) [2016-06-22 09:13:50 1958] DEBUG (XendDomainInfo:2504) XendDomainInfo.constructDomain [2016-06-22 09:13:50 1958] DEBUG (balloon:187) Balloon: 7602632 KiB free; need 16384; done.
