Hi,

I have observed that there is a maximum limit to the number of PV or HVM virtual machines you can start before dom0 hangs or crashes.

For Fedora 11 Linux x86-64 PV guests, dom0 will crash when I start the 7th instance. Max I can start is 6 without crashing.

For CentOS 5.2 Linux x86-64 HVM guests, dom0 will crash when I start the 4th instance. Max I can start is 3 without crashing.

I have 6 GB of DDR2-800 with Intel Pentium Dual Core E6300 2.8 GHz on Intel DQ45CB motherboard.

Are the above limits reasonable considering the hardware specifications of my computer?

I am using Xen 3.5-unstable changeset 20143 with pv-ops dom0 kernels 2.6.30-rc3, 2.6.31-rc6, 2.6.31.1, 2.6.31.4, and 2.6.31.5. My host operating system is Fedora 11 Linux x86-64.
