+Subject: [PATCH] esx: Allow connecting to IPv6 server
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When connecting to a VMWare server, the hostname from URI is
+resolved using esxUtil_ResolveHostname() which in turn calls
+getaddrinfo(). But in the hints argument, we restrict the return
+address to be IPv4 (AF_INET) which obviously fails if the address
+to resolve is an IPv6 address. Set the hint to AF_UNSPEC which
+allows both IPv4 and IPv6. While at it, also allow IPv4 addresses
+mapped in IPv6 by setting AI_V4MAPPED flag.
+
+Resolves: https://issues.redhat.com/browse/RHEL-138300
