Router VM fails to boot with kernel panic when overprovisioinig is > 1
Hi All,
When overprovisioning factors are > 1, the virtual router vm is not able
to boot and ends up in a kernel panic.
ACS_Version: 4.18.0
Storage: NFS
Any help would be really appreciated. Thank you!

Hi Sanjay,
This appears like a known issue: https://github.com/apache/cloudstack/issues/7430

Hello Sanjay,
What is the hypervisor, version you are using? If its KVM check whether the memory ballooning configuration is applied correctly and working as expected since you are using over-provisioning.
You could run ‘virsh dumpxml vm-name’ on the KVM as Vivek mentioned and look at the below values:
<memory unit='KiB'>1048576</memory>
<currentMemory unit='KiB'>524288</currentMemory>
You could look at the same using ‘virsh dominfo vm-name’ as well. I am not sure about the status of the ballooning configuration, hence please check that in the XML output. [1]

Hello Sanjay,
When you are doing over provisioning specially for memory, just go to the KVM node and see the output of dumpxml, you will see the memory assigned to the KVM guest divided by over provisioning factor, which means no suitable memory for OS to run ( if we use default offering ) ,
So try to increase the RAM in default offering or create a larger offering for VR.
