Right now the default hardware version for all ubuntu cloud images(such as ubuntu 18.04 cloud image, ubuntu 20.10 cloud image….) is VM version 10(ESXi 5.5).

If it's convenient to support having different VM hardware version for different cloud image releases, ubuntu 20.10 cloud image have default VM version 17 (ESXi 7.0) because vmware declare to support 20.10 desktop/Server in ESXi 7.0GA and later.

If Canonical’s strategy intend to let all cloud images have same default hardware version,
it' suggested to upgrade to default VM version 11 (ESXi 6.0) for cloud image.

It's suggested to change default hardware version of cloud image(.ova) to 13 (ESXI 6.5) or 11 (ESXi 6.0).

Thank you for opening this ticket. I've added it to the cloud-images project for prioritization.

Confirming this bug, as we've prioritized this work on our backlog. When we work on lp: 1898871, we'll ensure that the ova sets a serial port.

any news or plan for this functionality (LP 1898871) ? Thanks

Thanks very much.

"Serial Port 1" is added with ubuntu-21.10-server-cloudimg-amd64.ova
The default configuration about "Serial Port 1" is
   Serial Port 1: Use physical serial port
   Status: Connected at PowerOn

But with the default configuration it hit the problem:
  when power on the VM, I get warning message as follows:
     Cannot connect the virtual device serial0 because no corresponding device is available on the host. Do you want to try to connect this virtual device every time you power on the virtual machine?

Workaround:
It can be fixed by Setting "Connected at PowerOn" to false.

Thanks

This bug was fixed in the package livecd-rootfs - 2.748

---------------
livecd-rootfs (2.748) jammy; urgency=medium

  * live-build/ubuntu-cpc/hooks.d/base/ovf/ubuntu-ova-v1-vmdk.tmpl: do not
    automatically allocate serial0 as it causes a hang when upgrading.
