If you do not have xen-cmdline, then I believe the last time I did this was an xe command increasing the memory assigned to dom0's memory domain in the xapi. Here's an example command: xe vm-param-set uuid=<dom0 UUID> memory-static-min=8589934592 memory-dynamic-min=8589934592 memory-dynamic-max=8589934592 That's the number for 8gb by the way. --------------------------------------------------------- Brian S.

The first problem I had was the fglrx module not working well with the kernel provided by xen (blank screen after loading up), I solved it by adding this two lines in "/etc/default/grub": GRUB_CMDLINE_LINUX_DEFAULT="radeon.blacklist=1" GRUB_CMDLINE_LINUX="apparmor=0 nopat" I went with xcp-xapi solution instead of going straight with XenServer because i could use the my computer normally like there isn't a type 1 hypervisor running, but i can't reallocate more memory for my Dom0 host, right now I'm just using 1GB of my total 8GB, I want a minimum of 4GB if that could be possible, this is what I already done trying to solve this problem: - Added this line in "/etc/default/grub" (Of course I ran update-grub after that): GRUB_CMDLINE_XEN="dom0_mem=4G,max:4G" - Edited "/etc/xen/xend-config.sxp" with this values: (dom0-min-mem 4096) (enable-dom0-ballooning no) (total_available_memory 0) - Uncommented autoballoon=0 on "/etc/xen/xl.conf" - Tried to modify "/sys/devices/system/xen_memory/xen_memory0/target_kb" with the value I want but it keeps changing itself to 1297408. I run out of ideas, what else I can do? Thanks in advance for your time, have a nice day. _______________________________________________ Xen-api mailing list [email protected] http://lists.xen.org/cgi-bin/mailman/listinfo/xen-api ________________________________ The information contained in this message, and any attachments, may contain confidential and legally privileged material.
