Centos 7 & KVM Slave Node Issues
3 Attachment(s)
Running SolusVM VPS software on Centos 7 host node, as a KVM slave. Node keeps crashing, due to below but not sure how to resolve this.
See attached. I rebooted the slave, and second time in a row I tried to reset root password on newly created VM and it completely disables the entire NODE. I have to reboot again.
Code:
