[Xen-devel] Reporting some xen 4.1.2* and 4.0 issues like limitations to 4 VCPUs for debian squeeze HVMs etc

[Mark Schneider <ms@xxxxxxxxxxxxxxxxxxxxxx>]

Thank you very much at Pasi (pasik) for his kindly help!

<pasik> ironm: well you might want to report those to xen-devel mailinglist
<pasik> ironm: with exact software versions, and exact step-by-step 
instructions how to reproduce
<ironm> pasik, yes .. it is easy to reproduce as I have prepared two xen 
live images you can put on an USB sticks and boot from them:
rsync -avP 
rsync://www.it-infrastrukturen.ch/ftp/xen411-wheezy-kernel3-amd64-live-gnome-binary-hybrid.iso 
.
rsync -avP 
rsync://www.it-infrastrukturen.ch/ftp/xen40-squeeze-amd64-live-gnome-binary-hybrid.iso 
.
More details how I was testing are at:
http://www.it-infrastrukturen.com/fileadmin/linux/debian-live-xen/README.xen-live

<ironm> pasik, only HMVs images are on raid
   ACTIVE            '/dev/vg_xen/squeeze' [32,00 GiB] inherit
   ACTIVE   Original '/dev/vg_xen/wheezy' [32,00 GiB] inherit


Issue 1: 4 VCPUs limitation for squeeze?
# ---
<ironm> pasik, my problem was/is that HVM images for squeeze and wheezy 
created on xen 4.0 for some reason didn't boot on xen 4.1.2* ..
<ironm> pasik, when I create HVM images on xen 4.1.2* they can boot 
correctly .. however with some limitations for squeeze (not more than 
4VCPUs )
<pasik> ironm: do the images made on 4.0 boot properly on 4.1.2 if you 
have only 1 vcpu and say, 1 GB of mem?
<ironm> pasik, I had to install again . and this squeeze images boots 
now with 8GB RAM / 4cores
<ironm> pasik, I made tests with 1 core / 1 GB, 2 cores / 2GB and 4 
cores / 8GB .. they worked
<ironm> 8cores / 4 or 8 GB didn't work for squeeze

The error looks like:

Config files are like:
http://www.it-infrastrukturen.com/fileadmin/linux/paste/HVM/hvm-squeeze.born2b3.net.cfg
http://www.it-infrastrukturen.com/fileadmin/linux/paste/HVM/hvm-wheezy.born2b3.net.cfg

<ironm> pasik,  I will check if I can boot from HVM images (created on 
xen 4.1.2*) after rebooting xen 4.0
Issue 2: problem with too big install image size? (DVD images)
<ironm> maybe there is a problem when using DVD.iso images for 
installations .. (no problem with CD size )
<ironm> big size images (like DVD) or just the content (missing grub 
packages on them) causes install errors in HVMs
The error looks like:

Issues 3+: different errors in log files of xen 4.1.2*
