RE: how to start in qemu monitor window..

[ckim]

I tried giving ‘-serial telnet::3000,server’ and I can telnet to the machine through ‘telnet localhost 3000’.

But when I open another telnet session by ‘telnet localhost 3000’, it just gives me this prompt

Trying 127.0.0.1...

Connected to localhost.

Escape character is '^]'.

And doesn’t respond further.

Can anybody let me know how I can use multiple telnet session to the VM?

Thanks!

Subject: how to start in qemu monitor window..

 

Hello all,

 

I start my virtual machine with this command. (ubuntu 20.04 on arm64 virtual machine)

 

qemu-system-aarch64 -nographic -machine ab21q,gic-version=max,iommu=smmuv3 -m 1G -cpu max -smp 4 \

-netdev user,id=vnet,hostfwd=:127.0.0.1:0-:22 -device virtio-net-pci,netdev=vnet \

-drive file=ab21q-ubuntu-20.04-image.img,if=none,id=drive0,cache=writeback -device virtio-blk,drive=drive0,bootindex=0 \

-drive file=ubuntu-20.04-mini.iso,if=none,id=drive1,cache=writeback -device virtio-blk,drive=drive1,bootindex=1 \

-drive file=flash0.img,format=raw,if=pflash -drive file=flash1.img,format=raw,if=pflash

 

I want to run it with gui (actually being able to use multiple command terminal is enough). How can I run it in graphic mode?

When I remove ‘-nographic’ from the option, I see qemu monitor window and I don’t know how to start the machine from there.

I tried pressing ctrl-alt-f2 and I could see the VM starting with OS boot and I could later login but it was still a command window.

How can I create multiple command windows like we do in ubuntu graphical environment?

(I can use ctrl-alt-F3 or ctrl-alt-F4 to see anther command shell but this is not I want.)

And what is the command for booting the VM after I get in the qemu monitor?

 

Thanks for any helps..
