Chronology:

• Download VHD appliance from Zabbix.org
• Unzip and copy to the Cluster Shared Volume
• Create a new VM 1024Mo RAM, 1 vCPU, 1 NIC, No CD, connect the VHD as IDE
• Start the VM, get the Suse Logo.
• I log in with the root user into the appliance then start yast2
• Set up the Keyboard, the NIC, the NTP, and the DNS
  Seems good then open a web browser on a worstation and test the Zabbix portal. I can log in using the admin user account.
  All good.

Then I restart the VM.
I get the message:
Waiting for device /dev/disk/by-id/scsi-14d....-part1 to appear:..... Could not find /dev/disk/by-id/scsi-14d....-part1
Want me to fall back to /dev/disk/by-id/14d.....-part1? (Y/n)

I tried to press Y or n but nothing appends.
I then restart the VM, Select Advanced options for Zabbix_2.4_x86
Then select the first line Zabbix_2.4_x86_64_13.1 [ VMX ], with Linu

I got the same result.

I then restart the VM, Select Advanced options for Zabbix_2.4_x86
Then select the second line Zabbix_2.4_x86_64_13.1 [ VMX ], with Linu

And it works again, I was able to login on the Zabbix portal (web site).

If the Zabbix server is unable to boot alone, we are losing the entire Zabbix services until a manual intervention is done which could be long because some other critical apps are taking all the "recovery" time.

In the image, the "by-id" is used but it is not the best choice because the device ID is changing each time the image is mount on another "hardware" (including virtual hardware).

The resolution is:
Login as root:

fdisk -l

Disk /dev/sda: 64.4 GB, 64425615360 bytes, 125831280 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x42d970e7

Device Boot Start End Blocks Id System

nano /etc/default/grub

Change line 6 of /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT=" root=/dev/sd1 disk=/dev/sd1 resume=swap USE_BY_UUID_DEVICE_NAMES=1 quiet splash=silent"

grub2-mkconfig -o /boot/grub2/grub.cfg

Could you change this in the image to enhanced the friendliness?
