[BitVisor-devel-en:124] Re: Bitvisor Wireguard problems?

[Lonnie Cumberland]

Hello All,

I was able to set up and test to the point of the wireguard network 
crashing out and running in QEMU while having the bitvisor logs sent to 
the host (Ubuntu 22.04) but after multiple times, it did not yield any 
useful information that I could see:

Tested Guest OS's:

1. alpine-standard-3.20.0-x86_64 --- No GUI but tried to use "wget" to 
download a file from Github with no success. Knocks out the network.
2. debian-live-12.5.0-amd64-gnome, debian-live-12.5.0-amd64-gnome, and 
debian-live-12.5.0-amd64-standard  --- Started web browser and crashes
3. ubuntu-24.04-desktop-amd64 --- Started web browser and crashes

------------------------------------------

In one case, it just seemed to knock out the network which showed a 
configured device but no connection and could not restart the network.

I am still doing more tests and am searching for more possibilities as well.

Will update the ML if any progress is made on this.

Best Regards and have a great day,
Lonnie
