Hi Alamin, Ubuntu 16.04 has reached EOL in April 2021 (https://ubuntu.com/about/release-cycle), you should use Ubuntu 18.04 or 20.04.
Can you try running the following on Ubuntu KVM host: ln -s /etc/apparmor.d/usr.sbin.libvirtd /etc/apparmor.d/disable/ ln -s /etc/apparmor.d/usr.lib.libvirt.virt-aa-helper /etc/apparmor.d/disable/ apparmor_parser -R /etc/apparmor.d/usr.sbin.libvirtd apparmor_parser -R /etc/apparmor.d/usr.lib.libvirt.virt-aa-helper Ensure that the libvirtd was configured to listen on tcp/tls, for example: sed -i -e 's/\#vnc_listen.*$/vnc_listen = "0.0.0.0"/g' /etc/libvirt/qemu.conf sed -i -e 's/.*libvirtd_opts.*/libvirtd_opts="-l"/' /etc/default/libvirtd echo 'listen_tls=0' >> /etc/libvirt/libvirtd.conf echo 'listen_tcp=1' >> /etc/libvirt/libvirtd.conf echo 'tcp_port = "16509"' >> /etc/libvirt/libvirtd.conf echo 'mdns_adv = 0' >> /etc/libvirt/libvirtd.conf echo 'auth_tcp = "none"' >> /etc/libvirt/libvirtd.conf systemctl restart libvirtd After this restart libvirtd and try adding the host again. I've documented these for Ubuntu here that you can follow: https://rohityadav.cloud/blog/cloudstack-kvm/ Regards. ________________________________ From: pavan aravapalli <aravapalli.by...@gmail.com> Sent: Thursday, August 12, 2021 22:25 To: dev <dev@cloudstack.apache.org> Subject: Re: unable to add host ACS ubuntu 16.04 Hi, There could be multiple reasons behind “Unable to add the host”. Make sure you have configured the KVM host properly. In this case I see libvirtd daemon is running with error, try disabling apparmor module and re-add. Aslo "uefi.properties not found " is just an admin information and it will not cause any problem in kvm agent running. Regards, Pavan.
