VM is stripped down to minimum memory requirements (256MB) for owncloud. See below. Looks like a problem in virtio-net or a kernel bug with low memory situations.You're simply running out of memory. Yum can be a memory hog.
Yes, yum takes memory. But there is ~2.2 GB virt memory available. That should be enough. Therefore I think it is a kernel problem. As in previous crashes on the mailing list there is a lot of swap available (2GB) which isn't touched in ANY way.
Under normal conditions without yum: freetotal used free shared buff/cache available
Mem: 243036 132540 12716 15520 97780 74964 Swap: 2064380 0 2064380 And running it after reboot works fine (with all the services up). Ciao, Gerhard
