Install Xen

Dear *,

I want to install xen hypervisor in !# and related tools.
From the official Debian wiki (Squeeze) it says that installation can be done through a metapackage. Nevertheless, I get the following when giving it a try:

nuno@NINhOs:~$ sudo apt-get install xen-linux-system
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package xen-linux-system is a virtual package provided by:
  xen-linux-system-amd64 3.2+45~bpo60+1
  xen-linux-system-686-pae 3.2+45~bpo60+1
  xen-linux-system-2.6-xen-686 2.6.32+29
You should explicitly select one to install.

E: Package 'xen-linux-system' has no installation candidate

Any thoughts?
Thank you.
Cheers,
N.

Re: Install Xen

Hi again,

It seems that this will do the trick:

nuno@NINhOs:~$ sudo apt-get install xen-linux-system-2.6-xen-686
Reading package lists... Done

Reading state information... Done
The following extra packages will be installed:

  xen-utils-common xenstore-utils
Suggested packages:

Re: Install Xen

Hi *,

I still did not closed this ticket as resolved, because though I see the usual Xen stuff loading process on my screen, in the end I have a complete black screen. Cannot do nothing ... and have to force the reboot of the machine to another kernel.

Notice that if I load just the xen kernel without XEN 4.0 stuff (thus xend daemon not running) it loads correctly:

nuno@NINhOs:~/downloads$ uname -a
Linux NINhOs 2.6.32-5-xen-686 #1 SMP Sun Sep 23 13:33:12 UTC 2012 i686 GNU/Linux

Cheers,
N.

Re: Install Xen

Hi *,

A bit more of info to see if someone has crossed the same road and has knowledge to keep me in the right track.

Before you read this email, the simple question is.
Has anyone installed successfully Xen 4.0.1 (the one that comes with the !# stable release) in a Asus eeepc 1005HA or similar netbook?

A short overview of the steps taken up to the moment ... I installed Xen 4.0 32bits following the steps previously highlighted in this thread in a Eee PC 1005HA (with 2GB RAM). Yes I know, this is not a machine to do virtualization, but is good enough for testing purposes. As I said previously, booting into the 2.6.32-5-xen-686 kernel gives no problems, but if I boot to the xen aware kernel with Xen 4.0 (i.e. xend daemon is started during the boot sequence) I get a black screen.

After having a quick inspection in the dmesg log when xend service is started I noticed the following:

[    0.000000] Reserving virtual address space above 0xf5800000
[    0.000000] Initializing cgroup subsys cpuset

... snip ...

[    0.000000] ERROR: Unable to locate IOAPIC for GSI 9
... snip ...
[  172.602745] XENBUS: Unable to read cpu state

The booting process in fact hangs at this last line ... unable to read cpu state.

I'm guessing that I should go to the Xen mailing list and try there.
Already saw some postings with exactly he above xend problems associated to Debian distro's with exactly the same kernel version but up to know did not found a fix, if there's one.

Thank you.
Cheers,
N.

Re: Install Xen

To complement previous email in case it helps someone ...

If I boot the xen aware kernel it seems the CPU is recognized:

If I boot xen kernel with xend CPU is not recognized:

Re: Install Xen

Dear *,

In case someone is interested in ... for the records.
I was not able to figure out how to solve this. Several reports on debian distros running current stable kernel report the same, whithout no one providing a fix for this, at least I was not able to find none from the posts I read.

I moved to waldorf and installed xen 4.1.

nuno@NINhOs:~$ uname -a
Linux NINhOs 3.2.0-3-686-pae #1 SMP Mon Jul 23 03:50:34 UTC 2012 i686 GNU/Linux

nuno@NINhOs:~$ sudo xm list
Name                                        ID   Mem VCPUs      State   Time(s)
Domain-0                                     0  1887     2     r-----    264.7

Did not tested the #! stable release 32bits BPO.

Cheers,
N.
