[Tip] fast reboots with kexec

[psionic]

any updates for ProxMox 6?

Hi all.
Tried on proxmox 6.
after executing systemctl kexec it stops all VMs and seems to reboot as usual.
but after "restarting" i can't start\change config at all VMs. conf files are not writable.

Same here.

I was quite excited about kexec until I saw this note.

Anyone have it (or a similar solution) working on v6.2 ?

I love everything about my new Proliant server, except the 5 minute boot time.

Is there any progress on this issue, please? Is someone using kexec successfully?
Thanks.

EDIT: I've tried this and it works - https://patrakov.blogspot.com/2019/06/kexec-on-modern-distributions.html
