[Apologies if you receive multiple copies of this email]

Hi all,

We have noticed that the XEN server (the one providing you all with XEN
VMs) at the IG GPO rack is overloaded (it has around 86 VMs).

Experimenters with allocated resources might notice poor performance and
new slices requesting xen VMs at IG GPO will probably fail.

- If you have resources at the GPO IG rack but do not need them any
more please release them so that other people can use them

- If you can move your experimenter to another rack (there are many
underused IG racks out there:-)), it might be safer for you to do so

- If you need resources on the IG GPO rack but you keep failing,
please email he...@geni.net so that we can help you deploy your experiment.

We are working on finding a solution to this problem, in the meantime we
appreciate your understanding.

Best,
Niky Riga

For informational purposes, here's a current list of IG rack utilization for vms and containers for sites currently in the clearinghouse:

ig-illinois (Used: 15 Xen, 5 OpenVZ)

ig-stanford (Used: 8 Xen, 30 OpenVZ)

ig-cornell (Used: 3 Xen, 8 OpenVZ)

ig-missouri (Used: 14 Xen, 1 OpenVZ)

ig-northwestern (Used: 8 Xen, 8 OpenVZ)

ig-clemson (Used: 23 Xen, 15 OpenVZ)

ig-gpo (Used: 87 Xen, 42 OpenVZ)

ig-gatech (Used: 6 Xen, 4 OpenVZ)

ig-kettering (Used: 2 Xen, 27 OpenVZ)

ig-kentucky (Used: 17 Xen, 30 OpenVZ)

ig-nysernet (Used: 19 Xen, 6 OpenVZ)

ig-utah (Used: 4 Xen, 1 OpenVZ)

ig-utahddc (Used: 26 Xen, 0 OpenVZ)

ig-max (Used: 2 Xen, 1 OpenVZ)

ig-sox (Used: 3 Xen, 6 OpenVZ)

Note that lower numbers generally indicate more availability, although the UtahDDC site has 12 Xen nodes which makes it a great site to choose as it can support many more VMs than any other site.
