There is an issue  while importing a VM with a Basic zone network:\r\n- if you chose to set a random IP address:\r\n\r\n```\r\n2024-01-03 16:51:26,068 ERROR [o.a.c.v.UnmanagedVMsManagerImpl] (API-Job-Executor-10:ctx-bcae51d0 job-864 ctx-e872b0fb) (logid:016f507c) Failed to import NICs while importing vm: i-2-58-VM\r\ncom.cloud.exception.InsufficientVirtualNetworkCapacityException: Unable to acquire Guest IP  address for network Network {\"id\": 204, \"name\": \"defaultGuestNetwork\", \"uuid\": \"2c6b7a88-939a-42b1-8a5e-d9641071bff8\",\r\n \"networkofferingid\": 7}Scope=interface com.cloud.dc.DataCenter; id=1\r\n        at org.apache.cloudstack.engine.orchestration.NetworkOrchestrator.importNic(NetworkOrchestrator.java:4582)\r\n```\r\n\r\n- if you use a predetermined IP address the import fails with\r\n```\r\n\r\n2024-01-03 16:52:49,765 DEBUG [o.a.c.f.j.i.AsyncJobManagerImpl] (API-Job-Executor-11:ctx-a94ebd23 job-865) (logid:0f522606) Complete async job-865, jobStatus: FAILED, resultCode: 530, result: org.apache.cloudsta\r\nck.api.response.ExceptionResponse/null/{\"uuidList\":[],\"errorcode\":\"530\",\"errortext\":\"IP address 10.2.32.49 for NIC(ID: 0) is not available in network(ID: 2c6b7a88-939a-42b1-8a5e-d9641071bff8)\"}\r\n```\r\n\r\n2. If the storage pool is of type block for the volumes of an unmanaged VM, CS cannot find the pools. The select DB query tries to list by path and host_address which are taken from the libvirt XML disk definition and are not correct (for example it gets the volume path /dev/storpool-byid/bgu4.b.8wm instead of the actual primary storage path /dev/storpool-byid/. Also StorPool for example doesn't have a host described in the XML definition). Probably this issue will appear with similar storage plugins.\r\n\r\n3. Issue with VMs with RBD storage pool. You can unmanage a VM on Ceph storage but the listing of unmanaged VMs fails because libvirt cannot access the RBD volumes.\r\n\r\n```\r\n2024-01-04 11:56:55,383 DEBUG [utils.script.Script] (agentRequest-Handler-2:null) (logid:43ccc964) Executing command [qemu-img info -U cloudstack/d3638e01-955c-4702-8433-b62fe4bc680a ].\r\n2024-01-04 11:56:55,388 WARN  [utils.script.Script] (agentRequest-Handler-2:null) (logid:43ccc964) Execution of process [2868475] for command [qemu-img info -U cloudstack/d3638e01-955c-4702-8433-b62fe4bc680a ] f\r\nailed.\r\n2024-01-04 11:56:55,388 DEBUG [utils.script.Script] (agentRequest-Handler-2:null) (logid:43ccc964) Exit value of process [2868475] for command [qemu-img info -U cloudstack/d3638e01-955c-4702-8433-b62fe4bc680a ] \r\nis [1].\r\n2024-01-04 11:56:55,389 WARN  [utils.script.Script] (agentRequest-Handler-2:null) (logid:43ccc964) Process [2868475] for command [qemu-img info -U cloudstack/d3638e01-955c-4702-8433-b62fe4bc680a ] encountered th\r\ne error: [qemu-img: Could not open 'cloudstack/d3638e01-955c-4702-8433-b62fe4bc680a': Could not open 'cloudstack/d3638e01-955c-4702-8433-b62fe4bc680a': No such file or directory].\r\n2024-01-04 11:56:55,389 INFO  [resource.wrapper.LibvirtGetUnmanagedInstancesCommandWrapper] (agentRequest-Handler-2:null) (logid:43ccc964) Unable to retrieve unmanaged instance info. org.apache.cloudstack.utils.\r\nqemu.QemuImgException: qemu-img: Could not open 'cloudstack/d3638e01-955c-4702-8433-b62fe4bc680a': Could not open 'cloudstack/d3638e01-955c-4702-8433-b62fe4bc680a': No such file or directory\r\njava.lang.RuntimeException: org.apache.cloudstack.utils.qemu.QemuImgException: qemu-img: Could not open 'cloudstack/d3638e01-955c-4702-8433-b62fe4bc680a': Could not open 'cloudstack/d3638e01-955c-4702-8433-b62fe\r\n4bc680a': No such file or directory\r\n        at com.cloud.hypervisor.kvm.resource.wrapper.LibvirtGetUnmanagedInstancesCommandWrapper.getUnmanagedInstanceDisks(LibvirtGetUnmanagedInstancesCommandWrapper.java:191)\r\n        at com.cloud.hypervisor.kvm.resource.wrapper.LibvirtGetUnmanagedInstancesCommandWrapper.getUnmanagedInstance(LibvirtGetUnmanagedInstancesCommandWrapper.java:135)\r\n```\r\n\r\n\r\n##### ISSUE TYPE\r\n\u003c!-- Pick one below and delete the rest --\u003e\r\n * Bug Report\r\n\r\n\r\n\r\n##### CLOUDSTACK VERSION\r\n\u003c!--\r\nNew line separated list of affected versions, commit ID for issues on main branch.\r\n--\u003e\r\n\r\n~~~\r\ntested with https://github.com/apache/cloudstack/pull/8433\r\n~~~\r\n\r\n\r\n##### OS / ENVIRONMENT\r\n\u003c!--\r\nInformation about the environment if relevant, N/A otherwise\r\n--\u003e\r\nRocky linux 8.5\r\n\r\n\r\n","author":{"url":"https://github.com/slavkap","@type":"Person","name":"slavkap"},"datePublished":"2024-01-04T10:49:46.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/8439/cloudstack/issues/8439"}
