Re: [Xen-API] Guest Utilities

[George Shuklin <george.shuklin@xxxxxxxxx>]

If you running PV virtual machine, guest tools is simple formality. All 'guest tools' is consisted from few shell scripts, running in background (with few sleeps inside) and reporting information from VM to dom0. If you running HVM linux (why??), it should able to use PV drivers anyway (... I think so, never had that experience).

In short: all modern linuxes should ran on XCP without guest tools without any performance issues.

Trying to install guest utilities into a Linux VM, Ubuntu 12.04.1, installing from template provided by the default installation of XCP 1.6.1

Did not modify the template settings in any way, there is no way for me to even access the linux directory in the XS-tools.iso on the domU VM... I can see all the windows executables, and I see the linux directory folder, but I cannot access it, it "does not exist"

I followed several guides I could find online for xenserver 6.1, including the VM guide and several blog posts (all which were just mirrors of the guide), I am using XCP 1.6.1 as dom0,

I do not require ubuntu, I simply am looking to create a locally optimized VM that will act as a host...

Is there any documentation on the process of installing guest-utilities on a domU? What it does to the domU, and how long it takes?

I am just noticed that my XS-tools, is infact performing some tasks on the VM, I am going to let it be, as it is working extremely slowly, for it has been nearly an hour. How long does this process generally take? and is this what is suppose to show for domU guest optimization? It is running on a server I am aiming to be optimized for I/O, I just recently built it, it has 128gigs of ram in 16 slots with two CPU's at 3000ghz and 32 cores, should it take this long? Am I encountering a serious error?

here is output:

Thank you very much for any input, it is greatly appreciated,Â
