What's your experience on CCCQ on VM? Does it work?

    I have used CCCQ in many virtualized environments with no problems. For servers just as with a physical server you must spec it accordingly and most importantly ensure sufficient disk I/O performance. A virtual server with poor disk I/O will result in a world of pain for you and your users. Clients are not so fussy.

    Couple of quick tips...

    Tip 1: I generally avoid using VMs for build servers if possible. Build servers tend to use either 0% of available resources or 100%. At 100% you're competing with other VMs (potentially even your VOB + View servers!) and you'll get slower builds and subsequent whinging from users. Of course you can configure your virtual environment to use specific hosts/resource allocation but if you need to do that sort of thing you should consider a standalone build farm/physical build host anyway.

    Tip 2: If using VMware try and use the VMXNET3 virtual network interface, this does help with some latency issues caused by ClearCase's love affair with RPCs.

    Hello Jirong,

    Good day.

    Couple of tech docs about the Virtual machines with CC/CQ:
