Agree with this post here. Adding to this thought:
Outside of initial provisioning/firmware updates. This server should only need to reboot once a month for OS/firmware security updates and maintenance. Maybe less/more depending on your organizations security posture. OP said they’re running VM’s so I don’t understand the concern with the boot time. Once you provision the host you don’t really tinker with any setting unless your adding hardware to updating firmware/os.
If the boot time is really that big a deal, get a second host and setup replication/vmotion with your VM’s to eliminate the host boot time from affecting your uptime entirely.
It’s called the cyberwiper :D
