How to migrate server from LXC container to KVM/Hyper-V/BeraMetall?

Question

linux

Good afternoon friends!
There is such a task - to transfer a Linux server from an LXC container to a Hyper-V virtual machine.
I did the following.
1. Created a virtual machine in Hyper-V.
2. Installed Debian there with a minimum of packages.
3. Copied from the LXC container to the Hyper-V virtual machine with this command.
rsync --numeric-ids -avpogtStlHz --exclude-from="/root/exclude.txt" lxc-host:/ /
In exceptions dev proc run sys Run
command from Hyper-V.
After starting the virtual machine, the download is not complete. Authorization does not reach. If you boot into the recovery and make a chroot in /dev/sda1 , then the services can be started, everything works.
Please tell me how to do it right. Or how to fix what is.
