This is my first post in Oracle Forums, so I hope doing right questions to the experts who read my issue.
I´m working on a virtualized environment. I created and configured my "base environment" without any problem:
- Server 1: Oracle VM Server 3.2.2 (Clustered Server Pool: "POOL HA")
- Server 2: Oracle VM Server 3.2.2 (Clustered Server Pool: "POOL HA")
- Server 3: Red Hat Enterprise Linux 6 (Oracle VM Manager 3.2.2)
The next step is create several Paravirtualized Guests (Solaris 11 & RHEL 6). I'm able to create the VMs, but the problem is when I try to start them to install the OS...simply I can´t.
The error is as follows:
"Server error message: Command: ['xm', 'create', '/OVS/Repositories/0004fb000003000057155a18cb654250/VirtualMachines/0004fb0000060000fe3a960fd05eb708/vm.cfg'] failed (1): stderr: *Error: Boot loader didn't return any data!*
stdout: Using config file "/OVS/Repositories/0004fb000003000057155a18cb654250/VirtualMachines/0004fb0000060000fe3a960fd05eb708/vm.cfg"."
I´m trying to start them as shown in the Oracle's documentation (Using mounted ISO in http, ftp or NFS). I chose the http option:
In Server 3:
# cd /var/www/html
# mkdir EL5u6-x86_64
# mount -o ro,loop /path/RHEL6.iso EL5u6-x86_64
Network Boot Path = http://localhost/RHEL6.iso
- http Server is working ok
- localhost= Server3_IP
What am I doing wrong?, some kind of parameter in default vm.cfg file is missing?
Thanx in advance for your help!
You can't run Solaris or RHEL as PVMs. As far as RHEL goes, you can use OEL instead, which will - as of OEL6u3 run either as HVM or PVM.
Solaris however won't - and cannot run as a PVM, since the kernel is not even a Linux one.
So, if you must use RHEL, set both VMS to HVM and you're good to go.
Thank you very much for reply, maybe I misunderstood but according to next link, RHEL6 and Solaris 11 x86_64 can be a PVM guest on OVM Serverx86 (My OVM Servers run on 64 bits):
+"By default, Solaris 10 or Solaris 11 OS already has the required paravirtualized (PV) drivers installed as part of the OS"+ -Don't know if RHEL6 too.
+" Oracle Solaris 11 supports x86 64-bit architecture only. "+
http://docs.oracle.com/cd/E35328_01/E35329/html/vmrns-guest-os.html am I right?
The thing now is, I can start and seeing in "running" state my VMs. But I want to install the OS and VNC screen appears in black, I would expect to see the SO screen instead. Any idea?
I haven't recently checked with Solaris, but maybe Oracle has done some work to it. Would be interesting, since we're using Solaris quite a bit.
As far as RHEL is concerned - you can get RHEL to run as a PVM, but it needs some tweaking, that's why I suggested to go with OEL which provides that right from the start.
If the screen stays black, the VM isn't actually running I guess. I often start uo the VNC connection prior to starting the VM, because I want to see the startup of the VM. However, if you're running a PVM, you won't see anything until the system starts up.
Thanx for your comments budachst,
It's posible running RHEL6 & Solaris 11 as a PVM's, because I already have running both on my OVM Servers :D .
My screen was black just with vncviewer ( I don't know why) with tightvnc I could see the desktop of my VM through its console.
My problem has been solved.
