----------------------------------------
Summary: SystemVMs/VRs face kernel panic due to OOM on VMware
Key: CLOUDSTACK-10193
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-10193
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Reporter: Rohit Yadav
Assignee: Rohit Yadav
Fix For: 4.11.0.0
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.
