I Use terminator console to open multiple connections to the devices through telnet to the consoles, so I can type multiple commands simultaneously on multiple devices:

As soon as I type CTRL-C on terminator (to get out to the user mode on Arista/Cisco) The fololowing happens:

GNS3 breaks and tries to exit with this error qemu error:

I have to close GNS3 and restart it .

Any hint?

[grossmj]

Looks like you don't use the GNS3 VM. You could try to use our backported Qemu version 3.1.0 for Ubuntu 18.04.

If you wish to do so, please install our ppa then upgrade

sudo -E add-apt-repository -y ppa:gns3/qemu
sudo apt update
sudo apt upgrade

[grossmj]

As soon as I type CTRL-C on terminator (to get out to the user mode on Arista/Cisco)

Actually, looks like that terminator send a KILL signal to Qemu when you type CTRL-C (QEMU process has stopped, return code: -9)

I am not sure we can do something about that.

[grossmj]

@AJNOURI Have you tried with another terminal application?

[RocketWolf2020]

$ sudo qemu-system-x86_64 -m 512 -enable-kvm -usb -device usb-host,hostbus=1,hostaddr=7
output: qemu-system-x86_64: warning: host doesn't support requested feature: CPUID.80000001H:ECX.svm [bit 2]

Interesting that this failure/error message occurs for so many various unrelated reasons where the solution is for the user to change something to fix it.

Could we perhaps look into the cause of the error in the code? I'd really like to use Ventoy, but right now it fails in an epic manner and I can not recommend it to anyone.

[RocketWolf2020]

So I eliminated the warning message with the erroneous ECX.svm [bit 2] message by simply adding -cpu host to the command and changing 512 to 2048.

Now I only get the single error as follows:
$ sudo qemu-system-x86_64 -m 2048 -enable-kvm -cpu host -usb -device usb-host,hostbus=1,hostaddr=8
output: libusb: error [udev_hotplug_event] ignoring udev action bind

[Gelma]

So I eliminated the warning message with the erroneous ECX.svm [bit 2] message by simply adding -cpu host to the command and changing 512 to 2048.

Now I only get the single error as follows:
$ sudo qemu-system-x86_64 -m 2048 -enable-kvm -cpu host -usb -device usb-host,hostbus=1,hostaddr=8
output: libusb: error [udev_hotplug_event] ignoring udev action bind

Thanks a lot!

[alvinsmith-eroad]

-cpu host

thank you. just added -cpu host
