[Qemu-discuss] VNC port conflict
Hi, Recently, as I run the qemu command to bring up windows guest, it aborts with a vnc error $ qemu -m 3000 -cpu Opteron_G5 -hda qemu-vm/win2xpsp3_32_c.img -hdb qemu-vm/win2xpsp3_32_d.img -boot c -usbdevice tablet -enable-kvm -device e1000,netdev=host_files -netdev user,net=10.0.2.0/24,id=host_files,restrict=off,smb=/home/mahmood,smbserver=10.0.2.4 -vnc :1 qemu: -vnc :1: Failed to start VNC server: Failed to bind socket: Address already in use It seems that another user is using his own guest with vnc :1 saremi 31191 5.4 4.7 3624016 3133112 pts/31 Sl+ 12:00 14:10 qemu -m 3000 -cpu Opteron_G5 -hda qemu-vm/win2xpsp3_32_c.img -hdb qemu-vm/win2xpsp3_32_d.img -boot c -usbdevice tablet -enable-kvm -device e1000,netdev=host_files -netdev user,net=10.0.2.0/24,id=host_files,restrict=off,smb=/home/saremi,smbserver=10.0.2.4 -vnc :1 The same error exists for :2 but :3 is free. That mean, I have to ask all users which port they are using. Any idea? -- Regards, Mahmood
Re: [Qemu-discuss] VNC port conflict
you can run ps -eaf |grep vnc to see whcih all ports being reserved . or netstat comand netstat -tln|grep :59 On Sun, Jan 22, 2017 at 6:21 PM, Mahmood Naderan wrote: > Hi, > Recently, as I run the qemu command to bring up windows guest, it > aborts with a vnc error > > $ qemu -m 3000 -cpu Opteron_G5 -hda qemu-vm/win2xpsp3_32_c.img -hdb > qemu-vm/win2xpsp3_32_d.img -boot c -usbdevice tablet -enable-kvm > -device e1000,netdev=host_files -netdev > user,net=10.0.2.0/24,id=host_files,restrict=off,smb=/home/ > mahmood,smbserver=10.0.2.4 > -vnc :1 > qemu: -vnc :1: Failed to start VNC server: Failed to bind socket: > Address already in use > > It seems that another user is using his own guest with vnc :1 > > saremi 31191 5.4 4.7 3624016 3133112 pts/31 Sl+ 12:00 14:10 qemu > -m 3000 -cpu Opteron_G5 -hda qemu-vm/win2xpsp3_32_c.img -hdb > qemu-vm/win2xpsp3_32_d.img -boot c -usbdevice tablet -enable-kvm > -device e1000,netdev=host_files -netdev > user,net=10.0.2.0/24,id=host_files,restrict=off,smb=/home/ > saremi,smbserver=10.0.2.4 > -vnc :1 > > > The same error exists for :2 but :3 is free. > That mean, I have to ask all users which port they are using.

Re: [Qemu-discuss] VNC port conflict
>you can run ps -eaf |grep vnc to see whcih all ports being reserved Isn't there any easier way? Users are not expert, so do not expect to use ps command and see which vnc port is free... If I don't use vnc, the qemu will bring up the screen. So, the question is what is the benefit of using vnc? Bu using vnc, I have to open another terminal and connect to the guest Regards, Mahmood

This is how I addressed the need to try and select unique ports for the VNC and
Spice environments. This is from a Bash script used to start each VM.
#=#
# Spice and VNC Settings #
# #
# For each setting use the last octet of the primary MAC/IP Address in#
# decimal notation plus the port settings as the default setting. Thus for a #
# MAC/IP Address of 52:54:00:10:01:05/172.16.1.5 the settings would be: #
# #
#Spice Port (SPICEP) : 4 + (octet5*256) + octet6 #
#VNC Port : 5900 + octet6#
# #
# The octets converted to decimal notation. #

[Qemu-discuss] WinXP Guest: New hardware found - VGA controller
I'm trying Qemu (2.8.0) on Slackware GNU Linux 14.2 (64-bit) host. I've a Windows XP (guest) raw image which was working with Qemu times ago (I used it on an older Slackware version as host system). Now I launch qemu with the following command: - qemu-system-i386 \ -m 2G \ -net nic,model=rtl8139 \ -net user,smb=/mnt/share \ -drive file=newXP-15G.img,format=raw,index=0,media=disk \ -drive file=/tmp/ramdisk/ntfs-ramdisk-300M,format=raw,index=1,media=disk \ -enable-kvm - The system boots up regularly, but when it has almost complete, a "New Hardware found" pops up and it offer a search for the proper driver, then it doesn't find anything. If I look at Windows XP "device manager" I can see a yellow question mark on a device: "Video Controller (VGA Compatible)". If I well understood by reading Qemu man page, the default video card emulated should be a Cirrus model and it should be recognized by XP. Anyway I tried also to add: -vga std But also this time It can't be managed by any driver and device manager reports the yellow question mark also this time. Any suggest to solve? Thank you in advance folks! :)
[Qemu-discuss] Antw: Re: VNC port conflict
Hi,
the vnc option can handle the port dynamicaly with -vnc :0,to=x where the
next open port is used from 5900 on to 5900+x.
You then can get the used port via monitor command info vnc or assign it to a
variable
VNC_PORT=$(echo "info vnc" | socat - UNIX-CONNECT:${FILE_MONITOR} | grep
address | head -1 | cut -d\: -f 3 | tr -d '\r')
for further use.
