[neohal]

Hi All, Please your comments in the following issue:

Describe the issue: Creating an VM for Ubuntu x86_64 using Emulation. Starting the machine to initiate installation I got the following: "qemu-x86_64-softmmu: -netdev vmnet-shared,id=net0: cannot create vmnet interface: general failure (possibly not enough privileges)"

Configuration: UTM installed without any modification.

UTM Version: Latest version -> 3.2.4 (58)

macOS Version: Monterrey - 12.5.1

Mac Chip (Intel, M1, ...): Apple M1

Crash log: No UTM crash, error trying to start a VM.

Debug log: Attached debug.log file.

Upload VM: Attached config.plist file.

Appreciated any comment.

Thanks.

Sounds like you are using a version of UTM that does not have the virtual networking permission (entitlement). How did you install UTM?

It could be vmnet is busy, (possibly not enough privileges) could happen in UTM 4 if it crash... I had a similar but instead it was sharing...

Try to reboot your machine... or use bridge... with en0

Thx "conath", I´ve installed the file form mac.getutm.app and also I´ve installed from App Store the same results.

Thx "gustaf71", sorry for ignorance but how do I use bridge ?

You will find it at device network -> network mode (tab scroll), set the empty textfield to en0

I just had this same error, it was transient after shutting down a VM and then trying to start it afterwards. Failed 3 times then worked about 2 minutes later.

@Odaeus same here... did not work 2 times, searched the web, found this issue, retried -> worked again

Check with ifconfig if a bridge network in the same IP range already exists. Whenever I see this error, another app e.g. Docker, Fusion, Parallels, OrbStack.. already uses the same range (and UTM does not have enough privileges to take it over, hence the misleading error message...?)
