CISCO IOSv2 Infiniti boot loop

Post by SirStephanikus » Tue May 19, 2020 5:34 pm


I am trying out EVE-NG and compare it directly to the new Cisco CML 2.
However, as a first start I uploaded these 2 Images to /opt/unetlab/addons/qemu
and in their subdirs:
-- viosl2-adventerprisek9-m.SSA.high_iron_20180619/
-- viosl2-adventerprisek9-m.ssa.high_iron_20190423/

Later I renamed the qcow2 files to virtioa.qcow2 and ran this /opt/unetlab/wrappers/unl_wrapper -a fixpermissions.

EVE-NG directly recognize these images and I gave the Node 24 NICS ....on startup it runs than in an infinity boot loop like this:

Code: Select all

error: Can't get controller info..
error: Can't get controller info.Booted IOSv. Boot args: [/vios_l2-adventerprisek9-m]

Writing crashinfo to flash0:crashinfo_20200519-172551-UTC

When I remove the NICs and give them only 4 Nics, the node starts just fine.

What did I wrong ?
  • Wrong Settings like the qemu version ?
  • How can I get 24 Ports and in normal iteration like 0/1 - 0/24

vIOS supports up to 16 ports only

IOL switch supports more..
6x4port vards gives 24 ports, IOL !!!
