Hello,
Any idea why I get this issue on a Ubuntu 20 with cloudstack agent 4.15.1 ? If I leave just few flags I get the same, I only use the flags supported by CPU with guest.cpu.mode=host-model. 2021-08-21 07:53:38,395 INFO [kvm.storage.LibvirtStorageAdaptor] (agentRequest-Handler-4:null) (logid:b1023775) Creating volume c59d77d5-b08f-4e89-aed8-64dacf68a81f from template cb4db951-ab40-11ea-84e5-000c296a9f91 in pool fa5e174d-f4f6-43cd-b514-52dd5e652dc9 (Filesystem) with size (8.00 GB) 8589934592 2021-08-21 07:53:38,395 INFO [kvm.storage.LibvirtStorageAdaptor] (agentRequest-Handler-4:null) (logid:b1023775) Attempting to create volume c59d77d5-b08f-4e89-aed8-64dacf68a81f (Filesystem) in pool fa5e174d-f4f6-43cd-b514-52dd5e652dc9 with size (8.00 GB) 8589934592 2021-08-21 07:53:38,624 INFO [kvm.storage.LibvirtStorageAdaptor] (agentRequest-Handler-1:null) (logid:b1023775) Trying to fetch storage pool fa5e174d-f4f6-43cd-b514-52dd5e652dc9 from libvirt 2021-08-21 07:53:38,637 INFO [kvm.storage.LibvirtStorageAdaptor] (agentRequest-Handler-1:null) (logid:b1023775) Trying to fetch storage pool fa5e174d-f4f6-43cd-b514-52dd5e652dc9 from libvirt 2021-08-21 07:53:38,732 WARN [kvm.resource.LibvirtKvmAgentHook] (agentRequest-Handler-1:null) (logid:b1023775) Groovy script '/etc/cloudstack/agent/hooks/libvirt-vm-xml-transformer.groovy' is not available.
