VNC access to HVM Windows guest

Hi All,

Would you please be so kind and advise how to properly set parameters
for Windows 7 HVM?
Seems like i can start it, however can't get access to console via VNC.

All docs available online use different toolstack and I'm not sure how
to properly translate it to xapi settings.

Starting VM brings up qemu with following parameters
/usr/bin/qemu-system-i386 -xen-domid 33 -chardev
socket,id=libxl-cmd,path=/var/run/xen/qmp-libxl-33,server,nowait -mon
chardev=libxl-cmd,mode=control -nodefaults -name video -vnc
unix:/var/run/nonpersistent/xenopsd/xenlight/vnc/3ae49d0d-d255-b3ef-2bf4-80214a00f2c8,to=99
-display none -k en-us -serial pty -device cirrus-vga -global
vga.vram_size_mb=16 -boot order=dc -usb -usbdevice tablet -device
rtl8139,id=nic0,netdev=net0,mac=bb:bb:bb:81:bd:33 -netdev
type=tap,id=net0,ifname=vif33.0-emu,script=no,downscript=no -machine
xenfv -m 16368 -drive
file=/dev/xen/blktap-2/tapdev5,if=ide,index=0,media=disk,format=raw,cache=writeback
-drive
file=/dev/sm/backend/0e141376-6525-ff18-ffee-862446f5a617/0902f522-0e10-42c1-a438-fa5e7a17ba4c,if=ide,index=1,readonly=on,media=cdrom,format=raw,cache=writeback,id=ide-832

The important part is probably
video -vnc
unix:/var/run/nonpersistent/xenopsd/xenlight/vnc/3ae49d0d-d255-b3ef-2bf4-80214a00f2c8,to=99
-display none

And platform settings are showing VNC:
platform (MRW): timeoffset: 0; sdl: 0; vnc: 1; videoram: 16; vga: std;
nx: true; acpi: 1; apic: true; pae: true; viridian: true; device_id: 0002

Yet, I can't find system listening on any port.

The question is how to enable VNC on a specific port or next available
port as it is by default for PVMs?

Hi All,

Whilst I'm still looking for proper approach to the problem (getting the
qemu or xen to listen on selected port), I've manged to get tcp
connection to unix socket thanks to socat tool.

The example workaround looks like this run in a screen session or nohup,
etc.
socat -d -d TCP4-LISTEN:5910,bind=10.99.99.1,reuseaddr,fork
unix:/var/run/nonpersistent/xenopsd/xenlight/vnc/3ae49d0d-d255-b3ef-2bf4-80214a00f2c8

If any of you have idea how to force xenapi to force qemu to open tcp
socket, that would be great.

Thanks,
Dawid

Hey Dawid,

It's a security issue (open the VNC-port without authentication to the network). If you know what you are doing, I think socat is the way to go.

Some links that you may find interesting:
http://wiki.xenproject.org/wiki/Connecting_a_Console_to_DomU's
http://wiki.xenproject.org/wiki/Xen_Cloud_Platform:_Access_to_VM_console

Xapi offers a secure way to connect to the console. Have a look at the console-list RPC-call and have a look for the RFB-Protocol entries. The main problem for the average user is: You cannot connect your VNC client to this console without a proxy-script, that transports RDP via http :) A better idea would be to set up a VM that offers remote-management like https://xen-orchestra.com/.

Betreff: Re: [Xen-API] VNC access to HVM Windows guest

Hi All,

Whilst I'm still looking for proper approach to the problem (getting the qemu or xen to listen on selected port), I've manged to get tcp connection to unix socket thanks to socat tool.

The example workaround looks like this run in a screen session or nohup, etc.
socat -d -d TCP4-LISTEN:5910,bind=10.99.99.1,reuseaddr,fork
unix:/var/run/nonpersistent/xenopsd/xenlight/vnc/3ae49d0d-d255-b3ef-2bf4-80214a00f2c8

If any of you have idea how to force xenapi to force qemu to open tcp socket, that would be great.

Thanks,
Dawid
