It's a Quadcore machine..M$Hacks buying memory is not a problem but i looking for Cost effective(My company is ready to buy MEM's if i need to but I just think there has to be Workaround) solutions..Are U talking abiut Redhat with XEN,XEN Citrix or XEN running on Fedora core 5(The most stable instance i have found)..Running 20 Virtual Machines(Each with 1 GB Memory) sharing 8 GB pool of Memory is Interesting proposition..Isn't it?
I have Successfully Booted VM's from NFS..Running Single instance of NFS on FreeNAS is not the best idea.as i found, to compensate for the Disk Read/Write from NAS With NAS running Dual Core ..
And i came across another Problem..Windows 2008 Svr R2 is basically a 64 Bit OS..Running W2K8 R2 as Guest OS in Redhat 5.2 Enterprise Edition doesn't work..For some reason ,the product Freezed mutiple times during the Product Installation..To Overcome that problem, i had to hack through the Config File and made RHEL 5.2 with XEN think that it's W2K8 without R2..And i was successfully able to install the Product....
When u try to install XEN on Redhat, yes u have to virtually rebuild the Kernel..Which i also successfully did...There couple of dependencies but it was not that hard..
The problem that i encountered XEN redhat is the way u you backup the Machine to a Different Machine and it's not that easy..I have gone Through VMWARE ESXi 4.0 and the backup Procedure is fairly straight forward...I have to make sure that i install VMWARE central sever on Any machines and Should have Upto date VMware tools and Export the VM Instance..There is One Virtual machine HD and the Conf file that i have to backup..
Any ideas from Experts is Highly Appreciated..Virtulisation is an Interesting technology and U people can learn and have good career in this field..And No VM Experts on Desktop..i am Strictly talking about the SVR environment...
Thanks
