New subject: [libvirt PATCH 1/3] openvzDomainMigratePrepare3Params: correctly use hostname
In case no uri_in was supplied, we forgot to set the hostname
to the current hostname and formatted a useless uri_out.
src/util/glibcompat.h:57:26: error: ‘%s’ directive argument is null
[-Werror=format-overflow=]
57 | # define g_strdup_printf vir_g_strdup_printf
src/openvz/openvz_driver.c:2136:16: note: in expansion of macro ‘g_strdup_printf’
2136 | *uri_out = g_strdup_printf("ssh://%s", hostname);

New subject: [libvirt PATCH 2/3] openvzDomainMigratePrepare3Params: remove else after goto
We jump to the error label if the 'if' condition is true.
Remove the explicit else to make it more obvious that 'hostname'
is filled on both branches of 'if (!uri_in)'.
