Device stuck at boot/kexec

[aniruddha-a]

Hello,

I followed the steps here, and created a m3.small.x86 server instance, to that, I tried loading
my Ubuntu Bionic based custom ISO. I could see the VM booted up fine, I was able to also
access the serial console et al. But in the last step, the server didn't complete booting, I could
see that it was trying to load the kernel from my custom ISO, but was getting stuck somewhere
at kexec stage! (saw just a screenful of ? )
The server had UEFI, so I chose UEFI in KVM. Not sure what else could have gone wrong. I
could not configure the interface/PCI pass-through as I didn't see "Ethernet*" in the PCI.
What else can I check ? Is this recoverable or just have to discard and start over ?

Thanks.

Make sure the serial console kernel command line option is set to console=ttyS1,115200n8. If you see no output or it gets stuck in the kernel boot process then it's likely a driver / hardware support issue with the kernel you're using.
