GitHub user prashanthr2 added a comment to the discussion: Cloudstack Issue while creating instance in arm based host
@arpanbht VM start is failing as a result of below ``` tc qdisc add dev vnet0 root handle 1: htb default 1 Error: Specified qdisc kind is unknown. ``` Cloudstack tries to set network bandwidth for the VM nic to 200MBps (by default), this can be seen as part of libvirtxml as below ``` <bandwidth> <inbound average='25000' peak='25000'/> <outbound average='25000' peak='25000'/> </bandwidth> ``` Quick search on this tells me that HTB module is missing in the linux kernel. try below commands to see if the module exists lsmod | grep sch_htb if the above command returns nothing, try to load it manually as below. If modprobe fails as well. Install the package(based on your OS on KVM host) as mentioned here https://stackoverflow.com/questions/64755248/linux-fedora-tc-qdisc-gets-error-specified-qdisc-not-found and see if that resolves your issue sudo modprobe sch_htb If the issue still happens after installing the required package, send new set of debug logs after reproducing the issue.
