[jira] [Commented] (CLOUDSTACK-10193) SystemVMs/VRs face kernel
panic due to OOM on VMware

Commit af4668c5269752cb909a3c357a3e11015ba8fbb9 in cloudstack's branch refs/heads/debian9-systemvmtemplate from [~rohit.yadav@shapeblue.com]

CLOUDSTACK-10193: Use other64Linux for systemvms on VMware
In default/fresh installations, the guest os type for systemvms with id=15
or Debian 5 (32-bit) can cause memory allocation issues to guest. Using
Other Linux 64-bit as guest OS systemvms get all the allocated RAM. This
avoids OOM related kernel panics for certain VRs such as rVRs, lbvm etc.

> An edge case, systemvms use the guest os type 15 (or Debian 32-bit) which may lead VMware vCenter to not allocate all the RAM (default 256MB) to the guest. Via vCenter it shows that 256MB is allocated, but free -m (or cat /proc/meminfo) revealed that only 157MB was allocate in my testing against VMware 5.5 and 6.5. The fix would be to use a more appropriate guest os type that works for VMware 5.0+, other 64-bit Linux. We cannot use Debian7+ 64-bit as the guest os type is not available on older vCenter.
