GNS3 VM 2.2.43 on XCP-ng 8.2 seems to be working for me on HP G8 running 2 x Intel(R) Xeon(R) CPU E5-2690 0 @ 2.90GHz.

I havent really used GNS3 much so probably havent found what might be broken other than I cant load xen tools.

I just imported the OVA via XOA and pointed the windows GNS3 at the IP address it picked up.

@olivierlambert said in VM's going really slow after 3 - 4 weeks:

Oh wow. So something was wrong with the hardware, specifically the memory, and potentially more errors and error correction trying to keep up, slowing down everything. Is it a good recap?

To be honest I am not entirely sure.
I tested the memory my self in the early stages of this issue with memtest. In the past memtest has flagged memory issue that HP built in diags hasn't but it ran clean.

The server was rebooted prior to replacing the memory out of curiosity and everything came up OK no errors.

So we assume that something was wrong with the memory. And now we have are fingers crossed that that is the end if it

Hi Oliver,

My apologies I have wasted your time (though I did learn about the XOA so not totally wasted)

The old adage "If you want a job done properly. Do it yourself" is still very true.

Long story short when I looked into the issue myself, my colleague was using the wrong XO installation. This VPN isn't site to site so for now we have vmware running 2 nat'ed VMs, XO and a windows client. The windows client accesses XO and XO goes out over the hosts vpn connection to the remote site.

When using this correctly everything is OK
