Virtuoso and Spectre slow to start when VM is connected to the internet

StMano

Greetings everyone,


as stated in the title, I have Cadence Virtuoso & Spectre installed in a RHEL9 VM. Both are version IC6.18 and are activated with tools found in the forums here.
A small issue I am dealing with is that when the VM is connected to the internet (as in the network adapter is connected to the VM), it takes a good 10-15 seconds to start Virtuoso and for Spectre to start simulations. As soon as I deactive the network adapter, everything works perfectly.


Has anyone faced this problem? Are there any solutions?

Try it.
/etc/hosts
127.0.0.1       srv1.updates.synopsys.com
127.0.0.1       srv2.updates.synopsys.com
127.0.0.1       srv1.sw.synopsys.com
127.0.0.1       srv2.sw.synopsys.com
127.0.0.1       srv3.sw.synopsys.com

把虚拟机的网卡断开不就好了。

check the hostname of your VM。
i guess you are using the default localhost.localdomain
when connected to the internet, it might be automatically changed to sth. else. thus makes it slow....

Just disconnect the network card of the virtual machine.

That is the solution I am currently using, but I'd like to move the VM to an actual OS installation to remotely connect to. So internet access is required. Thus the question.

I have changed the default hostname, as it interfered with the license acquisition of some Synopsys tools (or something like that). Running hostname returns the hostname I have set, not localhost.localdomain.

很简单。。。因为你未把主机名写入host中。。。
