Unable to ping VM host (lima/colima)

[spkane]

Description

I setup networking for lima/colima a few weeks ago and it had been working fine, but today, even after some troubleshooting, I can not ping the colima VM from my host. I have updated lima, colima, and macOS with patch releases lately, so that might be related, but I am not really sure what to check at this point.

On the mac I can see this:

bridge100: flags=8a63<UP,BROADCAST,SMART,RUNNING,ALLMULTI,SIMPLEX,MULTICAST> mtu 1500
	options=3<RXCSUM,TXCSUM>
	ether 16:7d:da:6a:3e:64

	status: **active**

but I can not ping 192.168.105.1

One the colima VM, I can see this:

lima0     Link encap:Ethernet  HWaddr 52:55:55:74:18:4D
          inet addr:192.168.105.2  Bcast:0.0.0.0  Mask:255.255.255.0
          inet6 addr: fdce:1812:ad25:915f:5055:55ff:fe74:184d/64 Scope:Global
          inet6 addr: fe80::5055:55ff:fe74:184d/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          collisions:0 txqueuelen:1000
          RX bytes:42873 (41.8 KiB)  TX bytes:1720 (1.6 KiB)

and I can ping both 192.168.105.2 and 192.168.105.1

I'm not sure exactly what the next step would be in figuring out what bit is likely broken.

Pointers would be much appreciated.

I also posted this in lima-vm/vde_vmnet as I am not really sure where the issue lies. https://github.com/lima-vm/vde_vmnet/issues/37

This is what I see in the logs:

$ cat shared_switch.stderr.log
/opt/vde/bin/vde_switch: EOF data port: Interrupted system call
/opt/vde/bin/vde_switch: Reading  data: Connection reset by peer

I am noticing same behaviour, I get same error output when attempting to start vde_vmnet manually. And the vde_vmnet output looks like a fatal error

Initializing vmnet.framework (mode 1001)
start(): vmnet_return_t VMNET_FAILURE
start: Undefined error: 0

It is working fine for me again. I am still not sure how to reproduce this but I suspect it is related to network connections.

host and bridged networking seems to work fine, but shared is still exhibiting this issue consistently for me.

It's still happening to me as well with M1 shared won't work. But it's working with bridged.
