vmctl start missing disk

[Ted Unangst]

start a vm with a missing disk

vmctl start banana -d whatever -i 1
vmctl: start vm command failed: No such file or directory

that's not much of a hint what went wrong.

That's true,

there should be a proper error message in the future.

I came across the same error when starting a new VM. My problem was, that I
already used all 4 default taps that where generated by the installer (tap0,
tap1, tap2, tap3).

So I created a new tap device file and everything worked again:

/cd /dev; sh MAKEDEV tap4/

Then you can create a new tap device for each new VM that you start.

For more details see here (I tried to create a virtual network where each VM
responds to specific subdomain requests):

Jan,

Great page you wrote there. It's nice to know people are starting to use this.
