[Users] Problem Creating "oVirtEngine" Machine

--Apple-Mail=_DF4BF6D1-1F87-4F60-9CF9-070D4D836241 Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=windows-1252 I can't agree with you more. Modifying every box's or Virtual Machine's = HOSTS file with a FQDN and IP SHOULD work, but in my case it is not. = There are several reasons I've come to believe could be the problem = during my trial-and-errors testing and learning. FIRST - MACHINE IPs. THe machine's "Names" where not appearing in the Microsoft Active = Directory DHCP along with their assigned IPs; in other words, the DHCP = just showed an "Assigned IP", equal to the Linux Machine's IP, with a = <empty> ('i.e. blank, none, silch, plan old "no-letters-or-numbers") = "Name" in the "Name" (i.e. machines "network name", or FQDN-value used = by the Windows AD DNS-service) column. =20 if your IP is is appearing with an <empty> "name", there is no "host = name" to associate the IP, it makes it difficult to define a FQDN; which = isn't that useful if we're going to use the HOSTS files in all = participating machines in an oVirt Installation. I kept banging my head for three (3) long hours trying to find the = problem. In Fedora 18, I could't find where the "network name" of the machine = could be defined. =20 I tried putting the "Additional Search Domains" and/or "DHCP Client ID" = in Fedora's 18 Desktop - under "System Settings > Hardware > Network > = Options > IPv4 Setting" The DHCP went crazy; showing an "Aberrant-MAC-Address" (i.e. a really = long-sting value where the machine's MAC address should be), and we knew = the MAC address as we obtained using "ifconfig" on the machine getting = it's IP from the DHCP. So we reverted these entries from the = aforementioned, rebooted, and got an assigned IP, with proper MAC = address, but still no "Name" Kept wondering around the "Settings" and seeing which one made sense, = but what the heck, I went for it. =20 Under "System Settings > System > Details" I found the information about = GNOME and the machine's hardware. =20 There was a field for "Device Name" that originally had = "localhost.localdomain"; I changed the value to "ovirtmanager". and = under "Graphic" changed to "Forced Fallback Mode" to "ON". =20 I also installed all Kerberos libraries and client (i.e. authconfig-gtk, = authhub, authhub-client, krb5-apple-clents, krb5-auth-dialog, = krb5-workstation, pam-kcoda, pam-krb5, root-net.krb5) and rebooted VOILA=85!!! =20 I don;t know if it was the definition of "Device Name" from = "localhost.localdomain" to "ovirtengine", of the Kerberos libraries = install, or both. But finally the MS AD DHCP was showing the = Addigned-IP, the machine "Name" and the proper MAC-address. Regardless, = setting the machine's "Network Name" under "System Settings > System > = Details > Device Name", with no explanation of what "Device Name" meant = or was used for, was the last place I would have imagined this network = setting could be defined. NOTE - Somebody has to try the two steps I did together, separately. to = see which one is the real problem-solver; for me it is working, and "if = it ain't broke, don't fix it=85" Now that I have the DHCP / IP thing sorted, I have to do the DNS stuff. To this point, I've addressed the DHCP and "Network Name" of the = IP-Lease (required for the DNS to work). This still does't completely = explain why, by modifying the HOSTS file (allowing be to set and IP and = non-DNS FQDN). allows me to install the oVirtEngine "as long as I do not = use default HTTPd service parameters as suggested by the install". By = using the HOST file to "define" FQDNs, AND NOT using the default HTTPd = suggested changes, I'm able to install the oVirtEngine (given that I use = ports 8700 and 8701) to access the "oVirtEngine Welcome Screen", BUT = NONE of the "oVirt Portals" work=85 YET=85!!!

Is that = what you mean=85? oVirtEngine I will not be able to connect to the oVirt Nodes unless I = have DNS resolution, apparently means I should do something with = resolving via DNS in my home LAN (i.e implement some sort of "DNS Cache" = so I can resolve my home computers via DNS inside my LAN). feeling that it isn't always clear why things are going wrong, but in = this case I suspect that there is a rather small thing missing. hardware, and you give your host a meaningfull name AND you add that = info also in your /etc/hosts file than things SHOULD work, no need for = dnsmasq or even bind.
