There is a tool for checking state of VMs:

[userdom0 ~]$ qvm-check toto
usage: qvm-check [--verbose] [--quiet] [--help] [--all] [--exclude EXCLUDE]
[--running] [--paused] [--template] [--networked]
[VMNAME [VMNAME ...]]
qvm-check: error: no such domain: 'toto'
[user@dom0 ~]$ echo $?
2
[user@dom0 ~]$ qvm-check sys-net
qvm-check: sys-net: exists
[user@dom0 ~]$ echo $?
0

Best,
Frédéric

Thank you. I guess this should then do ...

if ! qvm-ls --running|grep -q $VM; then
  echo "$VM not running or present. Aborting."
  exit 1
fi

Ha - even better ... sorry, saw this late.

Thanks!

You know of `qvm-check`

`qvm-ls --running` will miss qubes that are starting up or closing down,
ie of state Transient.
To catch those, you need something like `qvm-ls |egrep 'Running|Transient'

Hi,

You maybe interested to know which VM is the last started (sometime
for DVM), here my way to do it :

virsh -c xen:/// list | tail -n 2 | head -n 1 | sed -r 's/^ [0-9]+ *//s .//'

qvm-check checks if for existence by default.
