A brief summary of my current problems after XEN installation:
First Problem: XL "Anything", be it INFO, TOP, UPTIME, whatever,
returns:
"
xc: error: Could not obtain handle on privileged command
interface (2 = No such file or directory): Internal error
libxl: error: libxl.c:109:libxl_ctx_alloc: cannot open libxc
handle: No such file or directory
cannot init xl context
"
You do not have /proc/xen/privcmd available in your environment.
Mount xenfs
(note to self - dust off my patch which makes that error message
more useful)
Second Problem:
My boot.log is showing:
"
[ [1;31mFAILED [0m] Failed to start Load Kernel Modules.
See "systemctl status systemd-modules-load.service" for details.
"
What extra information do you get by following the instruction?
Third Problem:
Today doing an apt-get update and apt-get dist-upgrade to
see if there was any major fix on stuff... and probably I am
with a Regression in hands:
"
Error found when loading /etc/profile:
/etc/profile.d/cedilla-brazil.sh: linha 21: [: n?mero
excessivo de
argumentos
As a result the session will not be configured correctly
You should fix the problem as soon as feasible.
"
Also trying to run "sudo su -" on terminal I get a
message saying I have too much arguments for (su) but since
it appears related to this problem above, I consider both
the same.
I don't see how this could plausibly be a Xen issue.
***I have already sent an e-mail to the Ubuntu mailing
list about this problem...
Fourth Problem:
I am receiving KERNEL OOPS messages saying my #4 processor
is pausing:
"
NMI watchdog: BUG: soft lockup - CPU#4 stuck for 23s!
[irq/19-b43:1082]
"
that is a strip from syslog, showing that message:

b43 (whatever it is) appears to be mad and is polling while in an rx
interrupt handler. It also appears as if your CPU is too hot and is
being thermally throttled.
