Insufficient memory & CVM is crawling require more memory...
In this post, we will look at how to increase CVM memory.
Before that, turn off the entire virtual machine before shutdown CVM.
[Get CVM name]
virsh list
[Get CVM properties]
virsh dominfo <CVMName>
[Shutdown CVM]
virsh shutdown <CVM Name>
[Change memory]
virsh setmaxmem <CVM Name> 12GB --config
virsh setmem <CVM name> 12 GB --config
[Start CVM]
virsh start <CVM Name>
That should do the trick!
