Cloudstack Issue while creating instance in arm based host

[arpanbht]

I have made a cluster which is arm based and trying to add nvidia jetson orin as a kvm host so its getting added to the management server and up and running.

But while creating a vm inside this host I am facing this kind of error

network/vnet/modifyvlan.sh -v 1460 -p -b br-1460 -o add ] failed. 2026-03-23 17:07:12,207 WARN [kvm.resource.BridgeVifDriver] (AgentRequest-Handler-2:[]) (logid:3bdbe4c7) Process [18707] for command [/usr/share/cloudstack-common/scripts/vm/network/vnet/modifyvlan.sh -v 1460 -p -b br-1460 -o add ] encountered the error: [Cannot find device "br-1460"/usr/share/cloudstack-common/scripts/vm/network/vnet/modifyvlan.sh: line 37: /proc/sys/net/ipv6/conf/br-1460.1460/disable_ipv6: No such file or directoryCannot find device "br-1460.1460"Failed to create vlan 1460 on pif: br-1460.]. 2026-03-23 17:07:12,211 WARN [resource.wrapper.LibvirtStartCommandWrapper] (AgentRequest-Handler-2:[]) (logid:3bdbe4c7) InternalErrorException com.cloud.exception.InternalErrorException: Failed to create vnet 1460: Cannot find device "br-1460"/usr/share/cloudstack-common/scripts/vm/network/vnet/modifyvlan.sh: line 37: /proc/sys/net/ipv6/conf/br-1460.1460/disable_ipv6: No such file or directoryCannot find device "br-1460.1460"Failed to create vlan 1460 on pif: br-1460. at com.cloud.hypervisor.kvm.resource.BridgeVifDriver.createVnet(BridgeVifDriver.java:338) at com.cloud.hypervisor.kvm.resource.BridgeVifDriver.createVnetBr(BridgeVifDriver.java:320) at com.cloud.hypervisor.kvm.resource.BridgeVifDriver.plug(BridgeVifDriver.java:239) at com.cloud.hypervisor.kvm.resource.LibvirtComputingResource.createVif(LibvirtComputingResource.java:3861) at com.cloud.hypervisor.kvm.resource.LibvirtComputingResource.createVifs(LibvirtComputingResource.java:3438) at com.cloud.hypervisor.kvm.resource.wrapper.LibvirtStartCommandWrapper.execute(LibvirtStartCommandWrapper.java:86) at com.cloud.hypervisor.kvm.resource.wrapper.LibvirtStartCommandWrapper.execute(LibvirtStartCommandWrapper.java:52) at com.cloud.hypervisor.kvm.resource.wrapper.LibvirtRequestWrapper.execute(LibvirtRequestWrapper.java:78) at com.cloud.hypervisor.kvm.resource.LibvirtComputingResource.executeRequest(LibvirtComputingResource.java:2280) at com.cloud.agent.Agent.processRequest(Agent.java:813) at com.cloud.agent.Agent$AgentRequestHandler.doTask(Agent.java:1295) at com.cloud.utils.nio.Task.call(Task.java:83) at com.cloud.utils.nio.Task.call(Task.java:29) at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) at java.base/java.lang.Thread.run(Thread.java:829) what is this error coming while creating an instance in this host give me solution

What is the problem? Cannot understand the error log.

I am not sure if this a ARM issue, but it's looking for a bridge with the name : br-1460 and that fails.

Are you sure this Agent is configured properly in the agent.properties?

yes we have configured the agent with cloudbr0 bridge which we have been doing with the x86 hosts, the normal instance making on the x86 is working peoperly but only for this arm based system we are facing this issue even we have added this host in a different cluster which is set to arm
