Please assist me with understanding this message. I get this same type of message for IOSv, CSR1000v, XRv and XRv9000
I have a new CML 2 install, and I'm new to this. I created a lab, and add some nodes, but when I click the play button on a node, I get the following message. What is causing this, and how do I fix this so that the nodes can start up?

it takes a team! myself, a linux sys engineer co-worker of mine, and the cisco tac, decided to reinstall cml 2.2.2... we all worked together and now my CML is working. i have csr1kv and xrv nodes booting. however, xrv9000 will boot, but the CLI/Console shows it rebooting over and over again... i'm guessing due to not enough resources. so i will try to see what i can do with xrv.

what kind of compute resources are allocated here for CML ? is there any other nodes running?
08-04-2021 03:30 PM
12 CPU
64 GB RAM
any idea why i can't get nodes to start ?

CML 2.2 ? if all node have same issue, suggest to reboot the CML (Linux and test )
I had the same spec I did not see the issue. ( I am running on Esxi 6.5 as VM)
is this the first time? or is this worked before?
here is thread can help you :

yes, CML Version 2.2.1 build36
yes, all nodes (csr1kv, xrv, xrv9k, iosv), same type of error (shown below).
vm was already rebooted...twice.
is there anything i should check in the CentOS Cockpit (tcp port 9090) ?
is there anything i should check in the cml admin qui dashboard?
that thread you shared with me seems to be a different issue.
when i try to boot any node, I see this error...

hey look what i just found. let me know what you think about this and if this is why i'm seeing those errors when i try to start nodes.
in this error message... it mentions...
Could not open '/var/lib/libvirt/images/virl-base-images/csr1000v-170302/csr1000v-universalk9.17.03.02-serial.qcow2': No such file or directory
when i log into the cockpit and go into "terminal" and i navigate to that directory, I don't find that qcow2 file mentioned in the above error. i only see a yaml file.

Before i go deep, is this Licensed Version ? is this full setup done ?
as you see thre is no Images in the folder to run the Labs ( device images need to download ?)
installation guide :

also check the post :

yes, this is licensed. 20 node personal license. full setup is done as far as I know. how do i get images into the folders? i thought the 10.5 BG refplat_p-20210511-fcs.iso file already had the images??
08-05-2021 03:39 PM
it does, there is a different ISO image here, can you post the ISO images you used to install here?
I may be missed here some information.
tell us your environment. (what CPU Intel ? or AMD ? ) ESXi ? VMware worksstation , VMware player ? bare-metal installation?

Sure i was guessing some installation issue, that is the reason i was stressing and asked for installation ISO images to make sure it the correct one. Glad all is good enjoy the Labbbbbing.
