<b>Subject:</b> [PVE-User] Problems booting PVE from USB Disk Drive<o:p></o:p></span></p>

<p class=MsoNormal><o:p> </o:p></p>
<p>Hello,<o:p></o:p></p>
<p>I seek your help in debugging a boot process that fails. Does PVE
have any "cheat codes" like Knoppix offers to manipulate the boot
process? Is there any way to pause the boot process so that I may read
the console messages to get a sense as to what is going wrong? If nothing
else, it would be great to change the retry period to something longer than 5
seconds so that I would be able to scroll back and read the console messages.<o:p></o:p></p>
<p>I am trying to create a bootable USB hard drive so that I can dual boot
Windows and PVE on my laptop. I believe that I need to dual boot rather
than run Windows as a guest because I use the laptop for performing and composing
music and the device drivers may not work well in a virtual environment.
But that may turn out not to be necessary after I conduct some side-by-side
performance tests. Until then, I have to use an external device because
PVE takes over the entire drive upon which it is installed and so it would
clobber my existing Windows.<o:p></o:p></p>
<p>I installed PVE 1.3 onto the USB drive and the installation appeared to go
pretty well. However, when I boot from the USB drive, it eventually
aborts with a Kernel panic after attempting to mount /dev/mapper/pve-root
on /mnt and gives-up ater 3 tries.<o:p></o:p></p>
<p>I tried to scroll back to see the console messages but don't get very far in
the 5 seconds that PVE gives me between retries. Scolling is no longer
possible once the Kernel quits.<o:p></o:p></p>
<p>Any advice on how to proceed from here would be greatly appreciated.
ProxMox is doing a two-phase boot so we should be able to boot from USB devices
once we can determine what is going wrong. For anyone interested in
learning along with me, here's a link to a good article on booting Linux from
external USB and Firewire devices: <a
