Dear Richard, Thank you for taking the time to reply to me. i have tested with "-x" option, but i cannot connect to Ceph Cluster. like this,
root@kvm-test-host:/home/test# virt-customize -x -a rbd:// 1.2.3.4:3300/test/test-base-img --hostname abc [ 0.0] Examining the guest ... libguestfs: trace: set_network true libguestfs: trace: set_network = 0 libguestfs: trace: add_drive "test/test-base-img" "readonly:false" "protocol:rbd" "server:tcp:1.2.3.4:3300" "discard:besteffort" libguestfs: trace: add_drive = 0 libguestfs: trace: launch libguestfs: trace: max_disks libguestfs: trace: max_disks = 255 libguestfs: trace: get_tmpdir libguestfs: trace: get_tmpdir = "/tmp" libguestfs: trace: get_cachedir libguestfs: trace: get_cachedir = "/var/tmp" libguestfs: trace: get_cachedir libguestfs: trace: get_cachedir = "/var/tmp" libguestfs: trace: get_backend_setting "force_tcg" libguestfs: trace: get_backend_setting = NULL (error) libguestfs: trace: get_backend_setting "force_kvm" libguestfs: trace: get_backend_setting = NULL (error) libguestfs: trace: get_sockdir libguestfs: trace: get_sockdir = "/tmp" libguestfs: trace: get_backend_setting "gdb" libguestfs: trace: get_backend_setting = NULL (error) libguestfs: trace: launch = -1 (error) virt-customize: error: libguestfs error: guestfs_launch failed. This usually means the libguestfs appliance failed to start or crashed. Do: export LIBGUESTFS_DEBUG=1 LIBGUESTFS_TRACE=1 and run the command again. For further information, read: http://libguestfs.org/guestfs-faq.1.html#debugging-libguestfs You can also run 'libguestfs-test-tool' and post the *complete* output into a bug report or message to the libguestfs mailing list. If reporting bugs, run virt-customize with debugging enabled and include the complete output: virt-customize -v -x [...] libguestfs: trace: close Actually, my question was how to pass the secret of ceph storage as a parameter when using uri pattern as follows. virt-customize -x -a rbd://1.2.3.4:3300/test/test-base-img add_drive "test/test-base-img" "readonly:false" "protocol:rbd" "server:tcp: 1.2.3.4:3300" "discard:besteffort" (how can i pass parameter "secret:{keyring}", "username:admin" in uri pattern?) i'm using qemu binary directly (qemu-system-x86_64) for using a VM instance, not through libvirt. So if I use libvirt, I expect it will take a long time to set up the VM because i have to add a domain to libvirtd. Thanks. 2024년 8월 10일 (토) 오전 12:46, Richard W.M.
