Nginx VM
-
@scottalanmiller I've just been using virt-manager and some ssh. I have Cockpit running on the host but haven't used it for management. It doesn't seem to reflect the guests that are running in the Cockpit gui. The cockpit-machines package is installed.

No, you have to either configure them for that, or build them through Cockpit for them to be seen there.

@scottalanmiller You are right. It is simple. I just worry that I will mistype a command and corrupt the guest. I worry a lot and over-think things way to often.
Same thing could happen if you mistype a PowerShell command on Hyper-V.

This is also why backups are mandatory.

Another question - Is there any reason NOT to use UEFI boot on all guests in KVM?
I wasn't able to create snapshots with UEFI VMs but that was from the GUI. I haven't using tried creating snapshots via command.
-
@black3dynamite I noticed that too. Did not try command yet either.
-
@scottalanmiller I'll concur about Windows here. I use a Win 10 vm made from virt-manager and its smooth as silk. Much better performance than using something like Virtualbox or hyper-V in my opinion.

There are two sessions, when creating VMs:
(QEMU/KVM) qemu:///systemand(QEMU/KVM user session) qemu:///sessionAre you log in with a user that is apart of the libvirt group?
Users that is not apart of the libvirt group will not see any VMs created in the system session. -
@black3dynamite I honestly don't know. I always use a normal user account and elevate privileges when necessary.

I know you can create the xml and tar a copy but there has to be an "easier" way.
That's so easy, I'm not sure what an "easier way" would really look like.
That is NOT as easy as one step. Period...

Just because there are fewer steps doesn't make those steps easier. So how much easier is it?
-
Is any platform really just one step? There is a lot of detail needed to move a VM from one machine to another. A single step can't account for all of that. I don't think Hyper-V or ESXi offer that, either.

In KVM, you can't snapshot UEFI VM's.

That's just poop.

oVirt provides a mechanism for moving VMs between the hosts.

Look under "Exporting and Importing Virtual Machines"

Do you know why?

On the IRC user group, I asked & was told it's a feature that has not been enabled.

@black3dynamite Found the thread, it was on the virt-tools-list not IRC.

OK, that's true - but really - please type out all of the exact steps to do it in KVM.
I've done it a few times (my first time actually) over the last few days in Hyper-V. it's all point and click in the GUI - and I'm sure with the commandline it would be like 100 characters .

@Pete-S said in Nginx VM:
I think 20GB is outrageously large. 8GB or preferably 4GB.
Thin provision though - so what does it really matter?
Not much but it increases the risk of starving other VMs if one or several VMs goes crazy since storage is overcommitted on thin provisioning.
A VM with ngnix reverse proxy and ssh goes in under 1 GB (on debian) so with 4GB storage there are already several GBs worth of unused space. What more do you possibly need?
That's why I think going to 20GB is just too much without any benefit. We are not running a desktop or windows are we?
If you want to do something completely different with the VM that requires more space you can just make a new one.
