I did a fresh Proxmox install on a dual Xeon CPU node with 64GB RAM. After booting it sits with the following error.

This same node had proxmox installed previously but with single Xeon without issue. To make sure something did not go wrong during installation i reinstalled Proxmox again but same issue. But i can SSH into the node, checked all services running. Any idea?

Re: Fresh Proxmox Install with /dev to be fully populated error

When the grub boot menu shows press 'e'. Then find the line where boot parameters are listed for the kernel. To this line add 'nomodeset' and press Ctrl-X to boot. The reason is that grub wants to insert a frame buffer to boot the console in high graphics mode but nomodeset ensures that grub boots using stdvga driver.

If this works simply change /etc/default/grub

uncomment '#GRUB_TERMINAL=console'
and comment 'GRUB_GFXMODE=some_Xxsome_Y

Then: update-grub

Huh! That was it! Adding nomdoeset worked. It booted to prompt just fine without /dev error.
I went to /etc/default/grub as your suggestion. It appears that both lines are commented. So i uncommented terminal console line and left gfxmode commented then rebooted. Issue was back.
So edited the following line /etc/default/grub and it rebooted just fine:
Changed from
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
To
GRUB_CMDLINE_LINUX_DEFAULT="quiet nomodeset"
Also i do not use allow-hotplug eth0 in interface config.

Thanks mir!!

OK. A problem with the i915 driver then. In that case you should apply it to GRUB_CMDLINE_LINUX instead to ensure it also adds nomodeset to maintenance mode as well.

Re: Fresh Proxmox Install with /dev to be fully populated error

I just installed Proxmox VE 3.4 and had the same problem: black screen after "Waiting for /dev to be fully populated". The graphics in my test system is integrated in the CPU (Intel Pentium G3220 - Hashwell architecture).
Editing /etc/default/grub and replacing
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
with
GRUB_CMDLINE_LINUX_DEFAULT="quiet nomodeset"
and running "update-grub" solved the problem.
I think it should be added somewhere in the Wiki ;)
