Are you sure the private key file corresponds to the root user? I see the same error when specifying a different keyfile, e.g. the qa-automation@suse.de one. But I see other problems when specifying root's keyfile:
error: authentication failed: authentication with private key '/root/.ssh/id_rsa' has failed: Unable to extract public key from private key file: Unable to open private key file
Hmm, the process trying to open the file is running as root. Using password auth works fine:
virsh -c qemu+libssh2://virt81/system?known_hosts=/root/.ssh/known_hosts hostname Enter root's password for virt81: **** virt81.devlab.prv.suse.com
IMO, this is not a virtualization problem, but one of correct key management for libssh2. Sorry I'm not familiar enough with the topic to provide suggestions. I can look deeper, but I suspect others (e.g. Marcus) will be more helpful.
Hi James, The private key of the root user is correct and it is generated manually, here is the test code: https://github.com/os-autoinst/os-autoinst-distri-opensuse/blob/master/tests... I downloaded the resource code of libvirt from GitLab and tried to compile the latest "GIT version" by using following command: ``` meson build \ -Ddriver_qemu=enabled -Ddriver_libvirtd=enabled -Ddriver_remote=enabled \ -Dlibssh=enabled -Dlibssh2=enabled \ --prefix=/root/usr ``` Referring the steps from: https://libvirt.org/compiling.html#building-from-a-git-checkout After that, I found the pub-key verification fail is on this line: https://github.com/libvirt/libvirt/blob/2ba73a10fd79637888235cfee8110fe2a21a... The function `libssh2_userauth_publickey_fromfile` failed to verify the public key. Then I found this issue about this function in the GitHub repo of libssh2: https://github.com/libssh2/libssh2/issues/659 Seems like that the bug has already fixed in the source code, but libssh2 did not release a new version until now. -- You are receiving this mail because: You are on the CC list for the bug.
