How to change the drive bus?

[g0drealm]

Hey guys,

i just started to engage myself with Proxmox and I hope you might help me with my problem.

I created a VM running Zentyal as a fileserver but i chose IDE as drive bus. I later recognized that i better chose virtio0 in view of performance.

How do I preferably change the drive bus to virtio? Can I convert the VM to a template and migrate it with other hardware specs?


Thx for your help

1) choose hardware tab for the VM
2) Click on disk
3) Click remove and as a result you should see an unused disk
4) Now double-click the unused disk and a GUI should pop-up where you can choose driver

Thx for your reply. Will this not harm the running system?

The system must be powered off before you can do it.

...just detached an IDE VM-HDD from Win 8.1 client and connected through SCSI. No system boot. I reverted this setting and... no system boot :O
Is there a possibility to get that VM once more running?

When I migrated my Windows-VMs over to PVE (from ESXi) once I have been in that state I needed to do the migration again.
I never got it working once I have been in that state.

This is how I got it working: Before you switch to SCSI (disk) you need to boot up in IDE. Then attach a virtio SCSI device. Install the drivers (virtio) and after that it was safe to switch the boot device to scsi and bring the (temporary) disk out of service

After changing the bus type by removing and re-adding the virtual disk, the boot option will have "lost" the drive. Navigate to "options" for the VM and set the disk as the first boot device.

You may need to attach as an IDE or SATA device first, set the boot option, and install virtio drivers for the controller in the guest OS as tburger suggested, (then install qemu-guest-agent while you're there), then shut down the VM, switch the disk to Virtio and reconfigure the boot order again.

Hi AllanM,

That did the job! That ide was deleted from boot sequence, after adding it and moving to 1st place VM is alive. Next step is to get qemu agent on all VM - thanks for your and tburger advise.

Best regards,

Wow. Thanks @AllanM
It seems I have totally overlooked that during my migrations.
