Parallels Desktop 17: Ubuntu 22.04 VM losts networking after Mac host wakes up

I just upgraded my Ubuntu 20.04 VM to v22.04, and notice that the VM losts network connection after the Mac host wakes up from sleep. The only way to bring it back is to reboot the VM. The problem does not repro with the original Ubuntu c20.04 VM. I have another Ubuntu 20.04 VM and it does not have the networking problem. Could it be caused by a change in the v22.04 kernel? Thank you.

 

Linux ubuntu 5.15.0-30-generic #31-Ubuntu SMP Thu May 5 10:00:34 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

 

Somehow the option of bridged networking is disabled. Is there a way to enable it?

 

I'm using shared networking mode, and it's fine so far with older Ubuntu VMs.

 

my version is 18.1.1 (53328), it has the same problem. guest os is ubuntu 22.04

 

Same here. Parallels Desktop Version 18.1.1 (53328) on macOS 12.6.2 running Ubuntu 22.04 LTS Server as a guest. As soon as the Mac (Macmini9,1 with Apple Silicon) goes to sleep and wakes up again the VM becomes unreachable. It's already using Bridged Networking with the adapter set to "Default Adapter" so this advice is of no use to me.
Any help would be appreciated

 

Anbody resolved this yet? (parallels 18.3.2, macos 13.4.1, ubuntu vm 22.04.2 LTS).
PLEASE DON'T TELL ME: "Configuration > bridged mode > select "Default adaptor" and check." COZ IT AINT THE SOLUTION. Try it out, it's so easy to re-create the issue.

 

A quick fix is to sudo dhclient which will renew your lease and get you connected, restore samba/filesharing etc without further irk (assuming you have a static assignment to the h/w address set at the router/dhcp server) - but for me the only solution is to reboot (the guest) every time the mac sleeps as so much else is borked (I'm running Plesk/DNS etc) - I don't think Parallels is really intended for serious dev purposes, just simple app compatibility and such

 

For me the solution is to run `sudo NetworkManager`, and that seems fix it perfectly. Perhaps there is a way to automate this?

 

NetworkManager is no longer the renderer in Ubuntu Server releases - just netplan and config of .yaml.

 

sudo dhclient works just fine on my end, but I wouldn't have a clue how to automate this from within the VM. The only automatable "solution" I came up so far was to whip up a command line tool running in the background (on the host) which reboots the VM every time the Mac wakes up

 

The problem also exists with Parallels 19.4.0 and Ubuntu 22.04 (5.15.0-112-generic). The workaround "sudo dhclient" works but is annoying and not a solution.
Are there any other approaches for a permanent solution?

 

I'm in the very same boat, and resolve as of yet?

 

Parallels 20 and Ubuntu 5.10 also suffers from this.
dhclient restores the IP, but all underlying stuff died in the meantime time, so having to reboot every time.
Running in bridged mode to wifi (which is the only active interface on my mac)
A real solution would be appreciated, also considering the wide spread of this years old issue.

 

I share your problem. But I tried to set up a vanilla Ubuntu and weren't able to reproduce the issue.

So I assume that some other things done to the Ubuntu setup seem to cause the issue. That's why it is NOT that easy to reproduce.

Me, I've installed paperlessngx in a docker container. To access the service, I set up a docker network and Caddy to support https access to paperless. It's just a vague idea, but maybe that causes the problem?

BTW: After waking up and calling "ip a", I can see IPv6 adresses on the interface, but no IPv4 anymore.
BTW*2: For me, calling "sudo netplan apply" solves the issue. Unfortunately, I haven't found a way to do this automatically on wakeup.

 

Very strange observation:

Since I installed the seconed vanilla VM yesterday, I cannot reproduce the problem, not even on the other VM running paperless-ngx.

Actually, it looks a little bit like a Parallels issue to me, now.
