We are experiencing performance issues with a VMware Server 2.x installation on an Ubuntu 8.04 host. When the host system is generating IO load (for example, copying large files as part of a backup operation), the guests (also Ubuntu 8.04) become extremely unresponsive and slow (simple Apache HTTP requests taking 5 seconds instead of the usual 200ms).

We tried optimizing various aspects of the VMs, but the issue remains. Is there a known bug with VMware performance under linux if host IO load is high? Is there a way to fix this? Is this only an issue with Ubuntu systems, or have you seen it on other systems before? Thanks!
