Am experiencing a weird behavior and wondering if anybody experienced something similar or has some hints/guidance about it.
On a server running XCP-ng, VMs (running Ubuntu 18.04) with nested virtualization ON are rebooting abruptly when Vagrant (2.2.14) is trying to bring up a libvirt/kvm “sub-guest” machine (NO issue if the machine uses QEMU rather… although too slow for the purpose!). The last line logged by vagrant before the XCP-ng VM restarts itself are something like:
==> vagrant-5-project-2-concurrent-0-job-681: Creating shared folders metadata...
==> vagrant-5-project-2-concurrent-0-job-681: Starting domain.
==> vagrant-5-project-2-concurrent-0-job-681: Error when updating domain settings: undefined method 'strip' for nil:NilClass
==> vagrant-5-project-2-concurrent-0-job-681: Waiting for domain to get an IP address...
==> vagrant-5-project-2-concurrent-0-job-681: Waiting for SSH to become available...
The VM just blows up and it reboots. It was working fine until some time ago. It looks like an update of XCP-ng might have broken it?
Anyone experiencing similar problems?
Is anyone able to provide some advice?
Thank!
