[ovirt-users] Re: HPE Oneview KVM appliance 8.8.0 / 8.7.0

2024-04-12 Thread Angus Clarke 
Hello again,



Uploaded the QCOW2 again and created a new VM from scratch with the expected 
parameters -> boots fine.



The failure scenario comes about when the original VM was set with Q35/UEFI 
with Virtio-SCSI disk type (completely fails to boot - expected) and then 
changed to I440FX with BIOS and change disk type to IDE. I'm not sure which 
change (or both) trigger the issue.

This failure scenario persists if I upload a replacement QCOW2 image and attach 
to the modified VM, including images from previous versions of HPE Oneview. 
This explains why I experienced repeat failures.



Overall this is probably not very interesting as this seems to revolve around 
IDE disk types - I'll feedback to HPE the Virtio-SCSI notes that Gianluca and 
Simon have mentioned.

Thanks a lot
Angus

Hi Gianluca



Thank you for the detailed instructions - these were excellent, I wasn't aware 
of the "lsinitrd" command before now - thanks!



My VM still sticks at the same point when booting with the virtio-scsi 
configuration. Meh!



I'm encouraged that the image booted ok in your environment => points to 
something specific to my environment.



I've raised a case with Oracle as we are using OLVM. I don't think they'll take 
an interest, let's see. If I get anywhere I'll report back here for the record.



Thanks again

Apart from other considerations we are privately sharing, in my env that is 
based on Cascade Lake cpu on the host, with local storage domain on filesystem, 
the appliance is able to boot and complete the initial configuration phase 
using your settings: Chipset i440FX w/Bios for the IDE disk type, OS: RHEL7 
x86_64. In my env graphics protocol=VNC, video type=VGA

The constraint for your tweaks is caused by the appliance's operating system 
where all the virtio modules are compiled as modules and they are not included 
into the initramfs. 

So the system doesn't find the boot disk if you set it as virtio or virtio-scsi.

The layout is of bios type with one partition for /boot and other filesystems 
on LVM, / included.

To modify the qcow2 image you can use some tools out there, or use manual steps 
this way:



. connect the disk to an existing rhel 7 / CentOS 7 helper VM where you have 
lvm2 package installed

In my case my VM has one disk named /dev/sda and the HPE qcow2 disk when added 
is then seen as /dev/sdb and its partitions as /dev/sdb1, ...

IMPORTANT: change the disk names below as it appears the appliance disk in your 
env, otherwise you risk to compromise your existing data!!!



IMPORTANT: inside the appliance disk there is a volume group named vg01. Verify 
there is no vg01 volume group already defined in your helper VM otherwise you 
get into troubles



. connect to the helper VM as root user



. the LVM structure of the added disk (PV/VG/LV) should be automatically 
detected

run the command "vgs" and you should see vg01 volume group listed

run the command "lvs vg01" and you should see some logical volumes listed 





. mount the root filesystem of the appliance disk on a directory in your helper 
VM (on /media directory in my case)

# mount /dev/vg01/lv_root /media/



. mount the /boot filesystem of the appliance disk under /media/boot

# mount /dev/sdb1 /media/boot/



.  mount the /var filesystem of the appliance disk under /media/var

# mount /dev/vg01/lv_var /media/var/



. chroot into the appliance disk env

# chroot /media



. create a file with new kernel driver modules you want to include in the new 
initramfs

# vi /etc/dracut.conf.d/virtio.conf

its contents have to be this one line below (similar to the already present 
platform.conf):
# cat /etc/dracut.conf.d/virtio.conf
add_drivers+="virtio virtio_blk virtio_scsi"



. backup the original initramfs

# cp -p /boot/initramfs-3.10.0-1062.1.2.el7.x86_64.img 
/boot/initramfs-3.10.0-1062.1.2.el7.x86_64.bak



. replace the initramfs

# dracut -fv /boot/initramfs-3.10.0-1062.1.2.el7.x86_64.img 
3.10.0-1062.1.2.el7.x86_64

. create a Red Hat 7.x VM in your oVirt/OLVM env as Q35 / Bios VM with the
appliance disk configured as virtio or virtio-scsi disk

. boot the VM and it should work, apart from the current problem of the
display in your env

Eventually if it boots ok and at the end it works, push HPE to add virtio
modules that are quite the standard for disk in Qemu/KVM based env.
The virtio network starts already ok because it is activated after boot as
a module and it is not needed in the initrd phase but only after it.

Is the image download publicly available? Or does it need any form of
