# grub.conf generated by anaconda I recently tried installing xen on another machine and I''m getting the "CPU0 is toast rebooting in 5 seconds" message. Reading through past postings, I was hopeful setting the dom0_mem=128M would solve the problem. Unfortunately, it didn''t make a difference. I haven''t fooled with anything on this system -- just a fresh FC4

Hi all, Recently I build XEN 4.1 (from the xen.org) on centIOS 5.5 (kernel 2.6.38.4). After changing the grub file and rebooting the machine, I am continuously getting out of memory error.

I''ve installed Xen Hypervisor 3.0.3 (CentOS 5.7, i386) inside Virtualbox 4.1.16 (Mageia 1, i686) and have noticed that Dom0 is consuming 85% of the memory allocated to the VM (1GB) so I''d like to reduce this as much as possible in order to make more room for one or two VM''s. Is there a minimum amount of vRAM that can/should be allocated to Dom0 (using the dom0_mem boot

The advice was backwards, you should really disable autoballoon if you use dom0_mem. Also add a reference to the command-line docs.

Hi, Can someone help. Ive setup xen on a fresh build but are having problems setting up grub. Ive run update-grub which has scanned the /boot folder and created the entries in /boot/grub/grub.cfg but im not sure how to add the dom0_mem=512M parameter?

Hello Xen Users, I am facing a problem getting my installation of XEN boot up on a Red Hat Linux Guest OS. What''s happening is that the grub loader tries to install Xen but after a while it crashes and starts rebooting recursively. I have tried both the entries listed below. I am using the following entries in the grub.conf file: title Xen-bhatia 3.0 / XenLinux-bhatia 2.6.16

Hello, I have a big startproblem with the dom0 kernel.

Hi All, I am running nevada 79 BFU''ed to 82. The machine is a Ultra 20 with 4GB memory. I have several Windows XP domU''s configured and registered. When ever I try to start the fourth domain I get an out of memory exception: Not enough memory is available, and dom0 cannot be shrunk any further Each of my domains only uses 256 so I thought there would be sufficient memory

Hello, I have some dom0 which have 8GB RAM, but when I look with xm list, it just shows me 6GB, I need to setup some new VM, each with 1GB, so I should have with 3VM still 5GB free, but im only seeing 3GB. Can I just create 2 new VM with each 1GB and still have 3GB for the dom0? #xm top xentop - 11:31:17 Xen 3.1.0-53.1.14.el5 4 domains: 1 running, 3 blocked, 0 paused, 0 crashed, 0 dying, 0

We''ve been looking in to support of 32bit domains on machines with large amounts of RAM. Working from the ballooning and reservation support added a few years ago: http://lists.xen.org/archives/html/xen-devel/2009-11/msg01277.html 32 bit domains eventually fail to boot with the following Xen complaint: xm create: Error: (4, ''Out of memory'', "panic:

Hy!     I''ve been trying to make Xen 2.0 work on a compac evo N800C laptop.

I want to install Xen 3.3.0 from source code. but I failed in doing that in the following steps 1. download xen from http://bits.xensource.com/oss-xen/release/3.3.0/xen-3.3.0.tar.gz 2. # tar -zxf xen-3.3.0;cd xen-3.3.0 3. # make world ......succeed 4. # cp /boot/config-2.6.18-53.el5 build-linux-2.6.18-xen_x86_64/.config 5. # make linux-2.6-xen-config CONFIGMODE=menuconfig (or xconfig)

Is there any reason why I would not want to set dom0-min-mem to 0 or to what I set dom0_mem on my kernel line? Setting to 0 or setting to the same value as dom0_mem disables memory balloon correct? I cant seem to think of a reason why I would want memory ballooning. Also setting dom0-min-mem should that be done in xend-config.sxp or on the kernel command line? -- Nick Anderson

Years ago when i first started using xen i specified a dom0_mem=xxx in grub. I no longer do this, what i do now is set the dom0_min-mem setting in xend-config.sxp to 1024. I also have a few scripts that run at boot and one of them does a `xm mem-set 0 1024`. after that a xm list 0 shows dom0 allocated 1024 Ram. The problem comes on teh system when i run free or free -m, free shows dom0

Hey all, just compiled xen 3.4.2 and linux 2.6.31.12. I followed the instructions on the Xen wiki to get the install running. my issue here is that in my grub memnu config i set dom0_mem=512M when i login to the dom0 and i do a free -m i get that the system only has 432 under the total section. booting into the stock debian kernel 2.6.26-2-amd64 kernel gives me 8192 free memory for i did

Hello friends! In this week, i had a problem with Xen version 3.0.2_09749-0.7 on SLES10 for x86, when the initrd-xen file was loaded. On console, various messages about "No space left on device" appears later that the "/dev" was monted on a tmpfs filesystem (for udev). The only sollution for this problem at that moment, was remove the "dom0_mem=192M" and the

Hello, I''m struggling to handle the amount of memory that dom0 gets on some system. It''s a system with 8GB of RAM, running 2.6.38-6 with pv_ops and Xen 4.1 If I want to set the amount of memory for dom0, I get very bogus results. See here: http://pastebin.com/gRgY9ERN If I use the M notation (xl mem-set 0 4096M) the outcome is similarily unpredictable, and sometimes I get the
