OK, I modified the /boot/grub/grub.confi file like you suggested. saved and rebooted. I got this first screen. I choose the zimbra option from the boot menu... Then got the error...

I was thinking that because the old default was the 2.6 kernel you would add that also... so you would have 3 entries in your /boot/grub/grub.conf:

Code: Select all

# resecue kernel and default
title CentOS 6 (2.6.32-504.el6.x86_64)
root (hd0,0)
kernel /vmlinuz-2.6.32-504.el6.x86_64 ro root=/dev/mapper/vg_zimbra-lv_root rd_NO_LUKS rd_LVM_LV=vg_zimbra/lv_root LANG=en_US.UTF-8 rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto rd_LVM_LV=vg_zimbra/lv_swap KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM rhgb quiet
initrd /initramfs-2.6.32-504.el6.x86_64.img

# first choice for the zimbra disk (old default configuration on other computer)
title Zimbra CentOS (2.6.32-504.12.2.el6.centos.plus.x86_64)
root (hd0,1)
kernel /vmlinuz-2.6.32-504.12.2.el6.centos.plus.x86_64 ro root=/dev/mapper/vg_mail2-lv_root rd_NO_LUKS LANG=en_US.UTF-8 rd_LVM_LV=vg_mail2/lv_root rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=128M KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM
initrd /initramfs-2.6.32-504.12.2.el6.centos.plus.x86_64.img

# Second choice for the zimbra disk
title Zimbra-2 CentOS (3.19.0-1.el6.elrepo.x86_64)
root (hd0,1)
kernel /vmlinuz-3.19.0-1.el6.elrepo.x86_64 ro root=/dev/mapper/vg_mail2-lv_root rd_NO_LUKS LANG=en_US.UTF-8 rd_LVM_LV=vg_mail2/lv_root rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=128M KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM
initrd /initramfs-3.19.0-1.el6.elrepo.x86_64.img


To recap... we have 1 disk with 2 partitions. The 2nd partition was created at the file copy level and is the concatenation of various partitions and was previously another computer. We commented out 3 lines form /home/etc/fstab as those partitions appear to be included in /home (the second partition) in this VM. Next we added 2 kernels to the /boot/grub/grub.conf and specified the disk to use is the second partition and where our root is for this computer. Note: we are using the /boot/grub/grub.conf from the first partition to make this work. That is why we are changing /boot/grub/grub.conf and not /home/boot/grub/grub.conf

Cool... getting closer. First read the other post I just sent about using the default kernel you previously had. I will double check the settings and you double check you cut/paste and didn't truncate or create partial lines. Those are 4 lines per entry for kernel in grub.conf

Hello Jim, Hope you had a great weekend.... OK, so picking up where we left off... we added two kernels lines from the /home/boot/grub/grub.conf on the second partition to the /boot/grub/grub.conf on the first partition of the virtual machine. since that failed. you wanted me to add more kernal lines.. correct? Here is the entire grub.config from the /home/boot/grub/grub.conf. shall I add all the kernels shown in RED ?
