downgrading RHEL to support IC 5141

Hello! Wondering if anyone else had to downgrade RHEL on a new workstation to support both IC 5141 and IC 61? What were the experiences with this? 

Seems quite a few foundries are still in IC 5141, listed in the supported platform matrix as requiring RHEL 4 / EOLd. New workstations are coming with RHEL 6 installed by default which isn't supported yet even for IC 61. So, to choose RHEL 5 even though Cadence doesn't officially support IC 5141 on it, or go down to RHEL 4 and be unsupported by RHN if there are issues in the downgrade such as missing drivers or libraries.

Any success stories or issues with taking either path would be appreciated. This is a Xeon X5687 with 24GB RAM, and there is plenty of disk space.

Cheers

    Not really sure why you'd need more than one virtual machine - you can use multiple PDKs and IC versions on a single machine or on a single virtual machine.

    Generally a guest VM can see the host - usually by the hostname of the host, provided that it is set up correctly. For example, there's no reason why your guest VM should not be able to access the hosts map via LDAP, if that's how you're doing it in general. Depending on the VM you use, you can set up the guest to be either NATed (and effectively appear on a private network), or in bridge mode and appear as another machine on the same subnet as the host (this is possible with both VMware and VirtualBox).

    There should be no performance hit with running the license server on the base operating system - the performance of a license server is generally not critical unless it is serving a very large number of license clients - the bigger impact will be the performance of the virtual machine itself - and usually that's just a matter of ensuring that it has been allocated sufficient memory.

    I also suggested that running RHEL5 should work, but not be supported (see my post earlier in the thread where I explain about support) - I work for Cadence. Note that "support" is somewhat a moot point with IC5141 because hotfixes have stopped (after all, it was released 8 years ago).

    I regularly use a VMware virtual host to run Cadence tools (although most of the time I'm running natively, and have a VMware machine with Windows 7 or Windows XP on it), and also use VirtualBox at home to run a guest Fedora VM on a Windows 7 host (this was straightforward to set up and install, but I don't run Cadence tools on it, as it's for personal use). I've not tried installing VMware myself.

    Regards,

    Andrew.
