Some issues with VMware Server 1.0.2 after upgrading to Ubuntu 7.04

First of all, thank you How to geek dot com and DebianAdmin for the "Upgrading Ubuntu From Edgy to Feisty (6.10 to 7.04)" procedure. All works fine.

Unfortunatly I get some error from the installation scripts because of some problem with module recompilation. I'm trying to troubleshoot the problems and I'll give you feedback asap (I'm a little overheaded with real work in this period...)

VMware Server 1.0.2 on Ubuntu 6.10

Hi all,
I've installed VMware Server 1.0.2 on my Ubuntu Box (AMD 64). I've also installed the 30 days trial of Virtual Center Server on a VM just to try it out. The installation on a 64 bits Linux release was not very easy because of lib32 required, but nothing that cannot be solved with some search on the Internet.

The first image is the XP desktop inside the linux box: on this client machine I've installed the Virtual Center Server for VmWare Server. The look and feel is very similar to Virtual Center 1.4 client (the one used with ESX 2.5.x farms) as you can see from second image.
There are the Inventory, Scheduled Tasks, Templates and Events button, to work easy on your virtual environments. If you're not familiar with ESX and you use only VMware Server you'll find that this tool is very useful.

The third image is about I/O performance monitor. You can see also the little counters for CPU, Memory (fifth image, see below) and Network performances.

The interface shows alarms from all virtual machines that are running in your VmWare Server Environment and the events tab for each system show what happened in the past.

All the performance graphs are configurable for look and feel: moreover you can define the lenght of analisys on which you want to have informations (past day, past week, past month or past year). Virtual Center server could be configured to use an .mdb database or MSDE or MS SQL Server.

As a final consideration, if you are a SMB, and you are a VMWare Server user, you'll be very happy with this product. It makes all the tasks easier to commit.

Cloning a Linux Machine with Converter

Hi all,
I've tried to clone a physical linux server (Fedora) with the VmWare Converter 3, and I do it. Unfortunatly cloning Linux with Converter is only experimental, and the application just clone the disk and you have to do all the manual task at the end of the cloning process in order to make the new VM works. I've followed the procedure that I've found in the http://www.vmwiz.com/ site and, as stated in the site, use process at your own risk.

First of all, if not installed, you should install the kernel source and utilities, on the physical machine.

Basically you have to reboot the linux machine with the Converter boot CD and clone it.
When this trivial task is finished, have a look at the settings of the VM on your Virtual Infrastructure client and do the needed change to reflect your "in mind" configuration.
Try to start the VM: quite soon you'll receive a kernel panic message. Swith off your Linux VM, and reboot it with a linux rescue CD. I've used Red Hat 7.2 disc 1 and at the boot: prompt write linux rescue.
Mount the installation, thet's pretty straightforward 'cause linux rescue option ask you if you want to do that, and mount your virtual disk as /mnt/sysimage. At the prompt do a chroot /mnt/sysimage.
Go to /etc/modules.conf and back it up: edit it removing all the physical SCSI driver that could be aliased in the file - replacing it with BusLogic driver.
Change directory to /boot and make a copy of your ramdisk(s) just in case of error... Issue the mkinitrd command for rebuilding the modules for the Buslogic driver (mkinitrd -f -v /boot/initrd-[version]-img [version]).
Halt your system. Disconnect boot cd connected for rescue procedure. Your system will boot up normally and you just have to install vmtools.

This procedure works for me but I cannot assure that's right for you.

Below you have some links on the subject.

TSX 2007 in Nice

Hi all,
last week I passed the VCP310 exam and I'm "relaxing" in Nice with a lot of VMWare professionals from all over the world.
This year the present seven different tracks to attend and three Labs with "hands on" session on Consolidated Backup, Perl Scripting, Lab Manager and Dunes.
Today I've met Mike Laverick (RTFM Education) and thanks him for his fantastic guides.

Keep in touch for news.
