Im on OpenVZ VPS which dedicated RAM is 128MB and burstamble RAM is 256MB.

"free -m" command shows 79Mb used free 176Mb free..

But when i upgraded to 256Mb dedicated RAM and 512Mb burstable. The yum install works without any issue.

If one dont want to upgrade RAM, solution can be installing software from source tar.gz archive or from .rpm file?
