How to upgrade a linux virtual server?

+3 votes
293 views

I plan to update my web server doing the following:

  • make a snapshot
  • change the linux repositories
  • make the upgrade

once I'm sure all is nice, delete the snapshot

Is it the good way? (I have all the space needed on the disk)

I'd go the extra mile and create an archived backup (perhaps compressed with 7zip / p7zip, using maximum compression -mx9 parameter) of the .vdi / .vdk or whatever disk image file you're using, before making the upgrade.

Exporting the machine in its current state as an ovf "appliance" and storing it on another (perhaps external) hard drive is also a good security feature.

But the above is just adding layers of redundancy. "just in case"

Let us say I want to create a LAN some members of which will be VMs and some physical machines. I want to server IP addresses to them using DHCP and I want them to share the same LAN address space (say 192.168.10.0/24).

Is there a way to do that? If so, what is it?

Does anybody know if it makes a difference to enable IP forwarding on the (linux) host? I know both works (enabled or disabled), but is there a good choice regarding the use of virtio_net inside the (linux) guests?
