Title:
[Microsoft Hyper-V guest] System shows graphic artifacts for a moment,
Thanks for the reminder! I just realized Ubuntu 20.02 was already
released on 4/23. We should try it.
For the CPU firmware (CPU microcode?) update issue: sorry, it's
completely out of my scope -- I only work on Linux. Hopefully that issue
will be resolved in the near future.

Honestly speaking two notes:
1. forget Ubuntu 19.10 -> there is LTS 20.04
2. after ca. 5 or 6 months Microsoft has not updated firmware for my CPU
in standard Windows Update packages and because of it I'm still not
interested in using HyperV (it's interfering with driver updating
microcode for
Sorry, I made a typo above: systemd.dsystemd.default_standard_output=kmsg ==>
systemd.default_standard_output=kmsg.
BTW, it looks systemd.show_status=true makes no difference for me. I don't see
any status info during the boot-up time -- not sure if I did something wrong.

I don't have much knowledge bout systemd, either :-) I just did a "man
systemd" and found the options of systemd. "man systemd" says that we
can use pass these kernel parameters to systemd:
systemd.service_watchdogs=true systemd.show_status=true
systemd.log_level=debug
Since Alt-SysRq-w gives nothing, I'm sure the long delay is not a
kernel/driver issue but a user space issue. It looks due to some reason
I just can not reproduce the long delay. :-(
In the Hyper-V Virtual Machine Connection window's "View" menu, there is
an item "Enhanced Session". In my Ubuntu
I followed your instructions of 4/21 regarding changing kernel
parameters and attaching PuTTY etc. Screenshot of the edited parameters
is next to your email attached (if attachment won't get published, I
will post online). I can send the PuTTY output, but I don't think we
learned anything we
I also tried xrdp mode and the VM booted up to the xrdp login window in
14 seconds, which is faster than the "native Xorg GUI mode" (which needs
30s)

Sorry, I did miss this part of your previous reply:

To clarify, I say the purple login screen is "more native" because
that's what I get on the monitor of a physically independent machine
(not a VM) running Ubunutu; naturally I do not get an (X)RDP screen on
that machine ever.

You missed that I did include the output of 'systemctl list-jobs' during
the crucial interval of delay.
I will follow your instructions regarding boot parameters etc. and post
results asap.

RPD (XRDP) protocol and accessing

reproduce the long delay of > 1 minute: the VM can boot up to the Xorg
GUI desktop in 26 seconds.
My Windows 10 has the same version info: Version 1909 (OS Build
18363.778).
At the grub screen, can you press 'e' and, manually
It looks #48 shows some service is causing the long delay -- can you try
'systemctl list-jobs' to see active jobs, as the "Hint" says? :-)

@msgallery: BTW, you mentioned 'The "restart" button is not functional'

mouse -- if we press Tab to focus on the button and then press Enter,
the VM should reboot. :-) I'll try to mention this to Hyper-V team, but

The "graphic artifact" is somehow caused by the "$vt_hanoff" kernel parameter
(check "cat /proc/cmdline").
If I manually remove the "$vt_hanoff" at the grub screen, I won't see the

Today I installed a Generation-2 VM (4 virtual CPUS, 4 GB memory) from the this

running the built-in "winver.exe" program.
The CPU type is Intel

I reproduced this with Win10 x64 up to date on 4/11/2020 and the stock
"quick create" versions of Ubuntu 18.04 and 19.10 as referenced and
selected from the Hyper-V manager. Default options all the way. No
updates installed after initial installation. This machine has AMD Ryzen

So let me summarize your findings on the same host of yours (I suppose
your VMs use the same config for the number of vCPUs and the memory
size. I also suppose you only tested Hyper-V Generation 2 VMs or you
confirmed Gen-1 vs. Gen-2 makes no difference):

Hi Dexuan,
Sorry for delay in answer - I have installed fresh Server 19.10
(installation is of course different - EFI partition setup by installer,
etc. etc.) and after kernel boot messages I've got immediately login
prompt.
After that I've done "sudo apt-get install ubuntu-desktop" and issue is
Can Ubuntu devs please try to repro the issue? I can not repro it. :-(
Hi M, I assume you can also repro the issue with a VM created from
scratch from the server .iso (see comment #28) with a minimal
installation? If yes, can you please share the vhdx file? If you
configure the disk size to 15GB
Dear Ubuntu devs,
issue was reported on 17.10 and still - Ubuntu 19.04 starts fast, Ubuntu
19.10 upgraded from 19.04 / installed from scratch starts very slow.
ANY IDEAS?

The typical boot-up time of my Ubuntu VM on Hyper-V is 20~30 seconds for
a Desktop version of Ubuntu, and 10~20 seconds for a Server version. I
tried Ubuntu 19.04 just now and it also took 20+ seconds.
I never achieve a boot-up time of 2s.
I do know Ubuntu can boot up fast in 2~3 seconds in WSL
Hi,
If possible, please try 19.04 or LTS 18.04 and compare startup time - my
guess is that it will start almost immediately and you will see, that
you already reproduced it :)
I'm sure let's say in 90% :) -> 28 seconds is looonnnggg (like I said,
I've got about 2 seconds for older Ubuntu).
--
Hi M, since I can not reproduce the delay issue, I don't know what I can
do now. :-(
Do you think if it's related to Xorg?
Can you install a new VM from scratch from the server .iso
(http://releases.ubuntu.com/19.10/ubuntu-19.10-live-server-amd64.iso)
and see if you can reproduce the same issue?
Hi,
Thanks for comments #25 and #26,
I don't know how fast is your machine, but on mine earlier (before
19.10) I had startup in just few seconds, now have this delay. Yes, this
is maybe not critical, but should be fixed, because can go into Ubuntu
20.04 ;)
Anyway, I'm using stock kernel 5.3 +
I'm not sure what exact issues you're reporting.
Your VM takes too much time to boot up? How long? "systemd-analyze
blame" should collect the info for your VM.
Your VM's screen is somehow messed up temporarily during the boot-up
process? Or the boot-up process is stuck in the "text cursor"
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
I've tried to (1) boot the same machine with kernel 5.0.0.32 (2) create
new machine without upgrading from 19.04
Results were the same, anybody?
