Hi List, I get the following error when trying to create a new vm. There is 1024MB total physcial memory on the machine with 320MB used. Error: I need 1045876KiB, but dom0_min_mem is 1048576 and shrinking to 1048576 KiB would leave only 1021888 KiB free.

Hi guys, First of all, sorry for my poor english. This is my first message at this list. I''m using Xen on several machines since last November. Right now I''m having a specific problems with 2 servers: both are losing the network on dom0 but all guest systems are still running fine. Looking at those dom0 logs I''ve discovered that sometimes linux kernel OOM-Killer

...822 1 1.4 For the domU''s I have 822 mb configured, the first runs, when I want to start a second domU, then xend bails out because of missing memory: xm create /etc/xen/vm/NFSPUBLIC Using config file "/etc/xen/vm/NFSPUBLIC". Error: I need 841728 KiB, but dom0_min_mem is 65536 and shrinking to 65536 KiB would leave only 302336 KiB free. I know for all four domU''s I do not have enough memory, but for two, it should work: 300 + 2*822 = 1944 < 2045 I don''t understand why xend thinks it needs the memory, how is this calculated? I also set d...

...(but better of course =D) except memory overcommitment. I know this feature has been included since Xen 3.3 but I have found almost no information about it. When I try to start a domain with more RAM then is available on the server I get the following message : *VmError: I need 1433600 KiB, but dom0_min_mem is 200704 and shrinking to 200704 KiB would leave only 1348320 KiB free.* Well I know it doesn''t have enough RAM, that''s the whole point. Do I need to enable something specific somewhere ? I am using the Jeremy''s 2.6.31 kernel (thank you whoever you may be !). Thank you...

Nah, RHEL 5.1+ supports 32-bit domU (PAE and non PAE) on 64-bit dom0. Actually RHEL Xen is 3.1 with the brain damaged 3.0 userland utilities. -Ross ----- Original Message ----- From: centos-bounces at centos.org <centos-bounces at centos.org> To: CentOS mailing list <centos at centos.org> Sent: Fri Feb 29 04:46:42 2008 Subject: Re: [CentOS] error creating Centos 5.1 x32 dum_U

Hi It''s my first experience with xen I would like to use a OS linux create by buildroot like a guest. I have a PC whit virtualizatin whit debian distribution and I install xen-linux-sysem on the PC. In this PC a VM doesn''t work correctly. I would like to know if exist a simple tutorial to configure PC and VM . Thanks in advance Luisa

Hi, we''re contemplating getting a large new server, where we will run a number of virtual servers. Are there any things we need to keep in mind in that case? Are there limitations on what a Xen system can manage? We''re talking about a 4 x Quad core CPU server with 64 GBs of RAM and a couple of terabytes of RAIDed SATA storage. -Morten (Re-sending this, as the first message
