I find, when trying to reach the console of a vm when booting it, vnc is slow to connect. Meaning I miss the Proxmox splash screen/bios and the opportunity to interact with a guest's boot menu. e.g. pfSense and trying to interrupt boot to get single user mode.
Is there something I can do to check/improve vnc connection time at guest startup?
Many thanks.
 
This may have been caused by unavailable DNS. If I access the PVE web UI by IP, rather than hostname, I am able to get much quicker VNC console access to the pfsense guest and so see the splash screen and get to the guest's boot menu.
I expected the desktop OS or web browser to have cached DNS sufficiently long enough for this not to be a factor but it does seem to make a difference.

Oops. I just realised I posted this in the wrong subforum.
