Hello,
I am trying to enable external vnc following this guide: http://pve.proxmox.com/wiki/Vnc_2.0
However I cannot connect; the vnc client (JollysFastVNC) says "connection closed" immediately. When I telnet to the vnc port, it says:
Escape character is '^]'.
unable to connect to socket '/var/run/qemu-server/999.vnc' - No such file or directory at /usr/sbin/qm line 53.
Connection closed by foreign host.
and indeed the file doesn't exist on the host:
ls /var/run/qemu-server
999.pid 999.qmp
when I check using ps on host, the kvm command is following:
/usr/bin/kvm -id 999 -chardev socket,id=qmp,path=/var/run/qemu-server/999.qmp,server,nowait -mon chardev=qmp,mode=control -vnc unix:/var/run/qemu-server/999.vnc,x509,password -pidfile /var/run/qemu-server/999.pid -daemonize -name template-ubuntu-12.04 -smp sockets=1,cores=1 -cpu host -nodefaults -boot menu=on -vga cirrus -k en-us -m 512 -vnc 0.0.0.0:9001,password -usbdevice tablet -drive file=/var/lib/vz/template/iso/ubuntu-12.04.1-server-i386.iso,if=none,id=drive-ide2,media=cdrom,aio=native -device ide-cd,bus=ide.1,unit=0,drive=drive-ide2,id=ide2,bootindex=200 -drive file=/dev/vg-drbd/vm-999-disk-1,if=none,id=drive-virtio0,cache=none,aio=native -device virtio-blk-pci,drive=drive-virtio0,id=virtio0,bus=pci.0,addr=0xa,bootindex=100 -netdev type=tap,id=net0,ifname=tap999i0,script=/var/lib/qemu-server/pve-bridge,vhost=on -device virtio-net-pci,mac=5E:70
A:7C:8E:44,netdev=net0,bus=pci.0,addr=0x12,id=net0,bootindex=300
the relevant line in /etc/inetd.conf is:
9001 stream tcp nowait root /usr/sbin/qm qm vncproxy 999
and 999.conf is:
bootdisk: virtio0
cores: 1
cpu: host
ide2: local:iso/ubuntu-12.04.1-server-i386.iso,media=cdrom,size=688428K
memory: 512
name: template-ubuntu-12.04
net0: virtio=5E:70A:7C:8E:44,bridge=vmbr0
ostype: l26
sockets: 1
virtio0: shared-storage-on-drbd:vm-999-disk-1,cache=none,size=20G
args: -vnc 0.0.0.0:9001,password
I tried both with and without password in 999.conf, but it doesn't make any difference.
Also tried to say 3101 (ie 9001 - 5900) as in the guide, but could not start the VM:
qm start 999
Failed to start VNC server on `0.0.0.0:3101'
I also tried the web console, and got the error "Network error: could not connect to server: localhost:5900"
Can someone please give a hint what to try?
Edit: I forgot to mention that I connect to the proxmox GUI through ssh tunnel, since this host is hosted at an external hosting company and the only mean to connect to the host is via ssh; other protocols/ports are blocked by firewall.
Edit2: some more info: when I run in host terminal:
/bin/nc -l -p 9002 -w 1000 -c '/usr/sbin/qm vncproxy 999'
and then connect to port 9002 using a vnc client, I got this error in the host terminal:
unable to connect to socket '/var/run/qemu-server/999.vnc' - No such file or directory at /usr/sbin/qm line 53.
it seems the problem is that the vnc socket somehow is not created...
thanks,
Tony
