Hello Didi & Sandro,

I have encountered following issue when attempting to deploy a host from the engine management.

Engine: Fedora 28

Host: CentOS 7.6.1810

engine.log error:

2019-04-14 14:08:35,578+03 INFO  [org.ovirt.engine.core.uutils.ssh.SSHDialog] (EE-ManagedThreadFactory-engine-Thread-2) [628278a7] SSH execute 'root@10.35.0.229' 'umask 0077; MYTMP="$(TMPDIR="${OVIRT_TMPDIR}" mktemp -d -t ovirt-XXXXXXXXXX)"; trap "chmod -R u+rwX \"${MYTMP}\" > /dev/null 2>&1; rm -fr \"${MYTMP}\" > /dev/null 2>&1" 0; tar --warning=no-timestamp -C "${MYTMP}" -x &&  "${MYTMP}"/ovirt-host-deploy DIALOG/dialect=str:machine DIALOG/customization=bool:True'

I managed to resolve it manually by installing following rpms over the host machine before reattempting to deploy again the host from the engine management:

python2-otopi

python2-ovirt-host-deploy

I should mention that both engine and host were built from git master branch and not installed using the release rpms themselves, however Nir can also testify there is an issue when trying to deploy a host from Fedora engines (29 in Nir's case and 28 in my case).

Thanks,

Amit
