Hi M, I can not reproduce the issue: just now I downloaded http://dt0cinyuc0rrg.cloudfront.net/ubuntu-19.10-desktop-amd64.iso and created a Generation-2 VM on Hyper-V with the .iso file. The VM boots up fast: it boots up to the Xorg desktop in 28 seconds with 1 CPU and 2GB memory, and in 21 seconds with 8 CPUs and 8GB memory.
I don't see anything unusual. I believe you're also using Generation-2 VM since your "lspci" returns nothing. FYI: I got the below in my VM: decui@decui-u1910-gen2:~$ uname -a Linux decui-u1910-gen2 5.0.0-32-generic #34-Ubuntu SMP Wed Oct 2 02:06:48 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux decui@decui-u1910-gen2:~$ dmesg | grep "Hyper-V Host Build" [ 0.000000] Hyper-V Host Build:18928-10.0-1-0.1044 decui@decui-u1910-gen2:~$ systemd-analyze Startup finished in 303ms (firmware) + 663ms (loader) + 1.087s (kernel) + 35.041s (userspace) = 37.096s graphical.target reached after 34.963s in userspace decui@decui-u1910-gen2:~$ systemd-analyze blame 31.530s plymouth-quit-wait.service 10.598s gdm.service 1.817s dev-sda2.device 944ms networkd-dispatcher.service 866ms NetworkManager-wait-online.service ..... decui@decui-u1910-gen2:~$ systemd-analyze critical-chain The time after the unit is active or started is printed after the "@" character.
