I'm pretty much a newbie when it comes to the Xen Hypervisor, either way I installed it on a dedicated server, I just removed OpenVZ since it was annoying me. So, I followed http://www.crc.id.au/xen-on-rhel6-scientific-linux-6-centos-6-howto/ however I got kind of stuck in the grub part and it wouldn't properly boot into the Xen kernel since xend wouldn't start properly, so I followed http://linuxnet.ch/groups/linuxnet/revisions/42a63/6/ and used it's grub configuration and slightly modified it, I have a local copy of my grub that I used.
title CentOS with Xen (188.8.131.52-1.el6xen.x86_64) root (hd0,0) kernel /vmlinuz-184.108.40.206-1.el6xen.x86_64 dom0_mem=1024M cpufreq=xen dom0_max_vcpus=1 dom0_vcpus_pin ro root=/dev/mapper/vg-root rd_DM_UUID=nvidia_jbbdgddd rd_LVM_LV=vg/root rd_LVM_LV=vg/swap rd_NO_LUKS rd_NO_MD LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=us crashkernel=auto rhgb quiet initrd /initramfs-220.127.116.11-1.el6xen.x86_64.img
It booted fine, seemingly so, until I checked a few bits and pieces out in "xm info".
total_memory : 2046 free_memory : 516
So then I logically went to check "free"'s output (in MB).
total used free shared buffers cached Mem: 1505 769 736 0 31 384 -/+ buffers/cache: 353 1152 Swap: 4031 0 4031
However I have 2GB of physical membory and only 1505MB is displaying.
Furthermore I'm not able to find the grub bootloader config anymore to boot into the normal kernel so I'm sort of stuck for ideas on what to do, my server provider charges $25 for a reinstall so.. yeah.
Any ideas, is this actually a problem or my lack of knowledge?
