Slow Linux Guest VM installation and Performance.


HOLGER IOSEFF KOETZ DAVIDS

Question

 

Hello, I would like to ask for help in a problem that has been breaking my head for weeks. I have a cluster with two IBM's X3950 M2, with 128GB of RAM, 4 processors, connected to a VNX 5300 via fiber network. My problem is this: The installation of any version of windows is done successfully and at an impressive speed. When I try to install a Linux distro (Ubuntu, Fedora, CENTos) the installation becomes extremely slow. I use an NFS share where I made ISO storage that comes from a 10/100 network. I believe it is not a network problem, because the windows ISOS are in the same share. I don't know what else to do, because I really need to be able to install Linux VM's in this cluster of 2 servers. Has anyone ever experienced this? Thank you for the tips

So the install is slow but the operation of the VM seems okay? How is pre/post XenTools speed look ?

No, the VM operation is so slow too.

I'd up the NFS rsize/wsize settings to something way higher than the default, which is typically very small. You want something like like 64k or even 128k or so.

Thx for help...

But the VM is slow too, so i believe it is the hardware
