Error handshaking with VNC: no suitable auth schemes found. server supported: []byte{0x1}

Hi

I run ESXi 6.7 in my Lab and tried to install an ubuntu vm into it.

There is no VNC on ESXi 6.7. Does some else faced same issues?

Any input kindly appreciated!

If you are deployed directly to ESXi you might need to run the following commands on your ESXi host:

# enable GuestIpHack to allow packer to determine the vm IP address before vmtools are installed
esxcli system settings advanced set -o /Net/GuestIPHack -i 1
# open inbound VNC connections on the firewall
esxcli network firewall ruleset set -e true -r gdbserver

I have also had to add '"vnc_disable_password": true,' as described on the following link:
https://www.packer.io/docs/builders/vmware/iso#building-on-a-remote-vsphere-hypervisor

Hope this helps.

Stan

Hi Stan

Thx so far... I did all those 3 steps you mentioned and I got over the VNC issue but now there is a new one as shown in screenshot:

I fixed it... Had to increase the amount of RAM allocation from 512 to 1024

So, this is solved so far!

Thx Stan !!!

[Stan Dorsett]

No worries. I'm glad it is working for you now.
