WAAS installation - Memory exceeding the maximum

[Axel Robbe]

Hi all,

I have a question regarding a WAAS install. After installing a brandnew SSD (msata) in a brandnew 4k ISR, i have issues completing the installation. The device has 4GB of memory and I'm trying to run the vWaas 750 profile installer with service waas enable.

Below are the errors i encounter:

Installing bootflash:/ISR-WAAS-6.4.3c.42.ova

*Dec 13 10:12:14.597: %IOSXE_VMAN-3-MSGINITFAIL: Failed to initialize required Virt-manager resource: VM [AUTOWAAS]: Install failed, unable to parse VM machine def

I don't know what this means. Where does the 512 MB maximum come from? There is practically no config on the device as it came fresh out of the box. Is there something I'm missing from this installation guide???

All help is sincerely appreciated.

The documentation was a bit unclear whether the VM or the platform had a requirement or recommendation of 4GB. I ended up plugging 16 GB of RAM in and an extra flash module of 16gb as well. This has helped to successfully complete the install.

One note though: Adding a RAM module of a different size will make the router unbootable. So, total memory needs to exceed 4GB with either 1 stick or 2 sticks of identical size.
