At the time, I was using the Ubuntu 8.04 LTS version and used the distro specific install through apt-get. Anyhow, I encountered a lot of problems with console logins. After searching the Internet, I found I wasn''t alone. I discovered a lot of patches required to fix login issues as well as problems with the shutdown of Ubuntu domains. You have mentioned both of these problems in your recent posts. I have sinced moved to Debian Lenny for Dom0 and all DomU machines. That change has made a huge difference in the stability I have experienced with Xen. However, I still had to add configuration variables to my config files to ensure the console matches between Xen and my Debian virtual machine. The instructions I used were on the Xen wiki website and was listed as a known issue with Debian. Despite those configuration changes, I sometimes still see the blank console as you described when using the xm console command. Whenever this occurs, I simply hit the enter key on the keyboard and the login prompt shows up on my console. It is by no means scientific and I don''t have a technical explanation for why this occurs. But it works and that is good enough for me in most situations.> > Before I do that xm list shows me the following output > > root@abhitech-desktop:~# xm list > Name ID Mem VCPUs State > Time(s) > Domain-0 0 364 1 r----- > 2547.1 > mydomU 2 64 1 -b----> 9.5 > root@abhitech-desktop:~# > > > and if I execute xm console mydomU then it gave me erro mydomU is not > installed where as > in the domains directory I have > root@abhitech-desktop:/workarea/xen/domains/mydomU# ls > data.img root.img swap.img > all the above files whose sizes are > > root@abhitech-desktop:/workarea/xen/domains/mydomU# du -ch ./* > 194M ./data.img > 719M ./root.img > 4.0K ./swap.img > 913M total >I also started out using disk image files.

Mounting should be done when the DomU is not running.

Thanks a lot for the reply by the time you replied luckily without any logical reason the xm console mydomU had booted then I executed apt-get install ubuntu-desktop linux-image-virtual lvm2 user-setup it took an hour to do a lot of downloads and since then it has been setting up a lot of things which I feel are the desktop environments of \ Ubuntu since you mentioned Debian so I am curious to know in terms of stability since today only I was able to finish downloading all my DVDs of Debian so in terms of stability did you felt it better than Ubuntu or any other distribution if I talk about Xen On Mon, Nov 16, 2009 at 11:13 PM, Thomas Jensen <tom.jensen@digitaltoolbox-inc.com> wrote:> On Mon, 16 Nov 2009 21:42:50 +0530, Tapas Mishra <tapas@abhitech.com> > wrote: >> I am installing domU image >> >> after executing the following command >> >> xen-create-image --hostname=mydomU --ip 192.168.1.22 --gateway >> 192.168.1.250 --netmask 255.255.255.0 --broadcast 192.168.1.255 >> --dist=jaunty --mirror=http://archive.ubuntu.com/ubuntu --size=4Gb >> --memory=64Mb --swap=128MB --arch=i386 --partitions=with-data --boot >> --passwd --role udev >> >> >> I get following message at the last >> >> >> >> Creating ext3 filesystem on /workarea/xen/domains/mydomU/data.img >> Done >> Installation method: debootstrap >> Done >> >> Running hooks >> Done >> >> Role: udev >> File: /etc/xen-tools/role.d/udev >> Role script completed. >> >> Creating Xen configuration file >> Done >> Setting up root password >> Enter new UNIX password: >> Retype new UNIX password: >> passwd: password updated successfully >> All done >> root@abhitech-desktop:~# Started new Xen guest: mydomU >> [/etc/xen/mydomU.cfg] >> >> >> Logfile produced at: >> /var/log/xen-tools/mydomU.log >> >> Now here is the problem since the terminal on which it happened cursor >> is blinking it is not even giving me the shell to log in or execute >> any command so someone on IRC suggested me to mount the images >> > I too started out using Xen with Ubuntu for both Dom0 and DomU machines. > At the time, I was using the Ubuntu 8.04 LTS version and used the distro > specific install through apt-get.

It was at this time that I encountered a lot of issues that required patching to make Ubuntu behave in the virtualized environment. Because of the patching I had done, each time an apt-get upgrade updated my Xen installation, I had to reapply the patches for Ubuntu. The stability issues I had weren''t specific to Xen. Nearly each time I upgraded Ubuntu, one of my underlying services (DNS, Email, Web Server, etc.) would go offline for what appeared to be mysterious reasons. Although I really like Ubuntu in a desktop environment, I began to feel that for my production servers, Ubuntu was a little too bleading edge. As a result, I moved to Debian Lenny and have not experienced nearly as many issues with package upgrades. It just works. I use the site How to Forge as a reference when beginning new projects. There are several tutorials for various distributions. There is a tutorial for installing Xen onto Debian Lenny at the following link. There are similar tutorials for Ubuntu as well if you decide to stick with that distribution. http://www.howtoforge.com/virtualization-with-xen-on-debian-lenny-amd64 If you feel like trying Debian, you may want to try the minimal Debian package (http://www.debian.org/CD/netinst/). It is a much smaller download but requires an Internet connection during installation. If you have questions that aren''t Xen specific, you can feel free to contact me off list. Within reason, I can try to point you to resources that I have found useful.> On Mon, Nov 16, 2009 at 11:13 PM, Thomas Jensen > <tom.jensen@digitaltoolbox-inc.com> wrote: >> On Mon, 16 Nov 2009 21:42:50 +0530, Tapas Mishra <tapas@abhitech.com> >> wrote: >>> I am installing domU image >>> >>> after executing the following command >>> >>> xen-create-image --hostname=mydomU --ip 192.168.1.22 --gateway >>> 192.168.1.250 --netmask 255.255.255.0 --broadcast 192.168.1.255 >>> --dist=jaunty --mirror=http://archive.ubuntu.com/ubuntu --size=4Gb >>> --memory=64Mb --swap=128MB --arch=i386 --partitions=with-data --boot >>> --passwd --role udev >>> >>> >>> I get following message at the last >>> >>> >>> >>> Creating ext3 filesystem on /workarea/xen/domains/mydomU/data.img >>> Done >>> Installation method: debootstrap >>> Done >>> >>> Running hooks >>> Done >>> >>> Role: udev >>> File: /etc/xen-tools/role.d/udev >>> Role script completed. >>> >>> Creating Xen configuration file >>> Done >>> Setting up root password >>> Enter new UNIX password: >>> Retype new UNIX password: >>> passwd: password updated successfully >>> All done >>> root@abhitech-desktop:~# Started new Xen guest: mydomU >>> [/etc/xen/mydomU.cfg] >>> >>> >>> Logfile produced at: >>> /var/log/xen-tools/mydomU.log >>> >>> Now here is the problem since the terminal on which it happened cursor >>> is blinking it is not even giving me the shell to log in or execute >>> any command so someone on IRC suggested me to mount the images >>> >> I too started out using Xen with Ubuntu for both Dom0 and DomUmachines.>> At the time, I was using the Ubuntu 8.04 LTS version and used thedistro>> specific install through apt-get.
