Do you have the latest VMware tools installed in this VMs?
Also are they using any resource limits, or Pools etc??
Openvm tools version 9.10.2 are installed. We tried installing VMWare Tools latest version (10.0.6), no change.
There are no resource pools, limits or reservations, also, there is no contention for memory on the host (around 40% memory used)
Kind regards, Vjeran
are you able to fix this?
To simulate your issue, I deployed CentOS 7.1 with minmal packages and GUI. with 2 GB RAM. 2 vCPU.
After first successful boot, I configured RAM to 42 GB and VM powered on without any issue.
Did multiple reboot, power off, Power on and did not observed any issues.
Try install latest updates of CentOS in VM.
below is my config -
Kernel - Linux Centostest 3.10.0-229.el7.x86_64
OS - CentOS 7.1 x86_64
Open VM tools installed.
vCenter 5.5 and ESXi 5.5 Build 2143827
Thanks for your response.
No, I did not find a solution.
My environment is similar, but not identical: vCenter is 6.0 Update 1, ESXi is 5.5 Build 3343343, and linux kernel is 3.10.0-327.13.1.el7.x86_64.
Originally, openvmtools were installed, I tried with VMWare Tools (latest version) but there was no change.
Just to confirm, did you do guest os reboots (two in a row), either using VMtools or from "inside" the guest os? Because "hard" reboots work every time for me.
Kind regards, Vjeran
yes, I did multiple reboot from within Guest OS and from VMware Client.
I don't see this as a VMware issue, check your Guest/CentOS settings, update kernel...etc.
I am not sure if it is a VMWare or Linux issue.. I tried the same thing with a Windows VM and it works ok, but they also tried a Centos VM on KVM and it works ok..
And it's not like we have support for Centos to raise a case
I am seeing the same issue but with any amount of memory larger than 64GB and have been able to reproduce it consistently on ESXi 5.5 up to build 4178633 with both CentOS 6 and CentOS 7. I am not having the issue in ESXi/vCenter 6.0.
Dell PowerEdge R730
ESXi 5.5 builds 3116895 & 4178633
CentOS 6 & CentOS 7
Power on = OK
1st Reboot = OK
2nd Reboot = Hang
As it hangs immediately after grub, I don't think it has much to do without VMware Tools.
The thing I would check are:
- CPU masks if you have applied any
- The virtual hardware version, use at least version 8.
