[Xen-users] a bug of xen?

[yibin.shen <freedoooooom@xxxxxxxxx>]

Hi,all,

we use xen3.0.3 and compiled the 2.6.16.29 kernel for both Xen0 and XenU on CentOS 4u4 x86_64,

it works quite well and stable for almost 2 years,

but when I build Xen and kernel on CentOS 4u4 i386 platform with same configuration,

some strange happens,

if I put XenU(CentOS 4u4 system) on image file (used dd command,and the mem is set to 512M),

then if image file is less then 2G, the XenU can boot successfully,

but if it larger then a value,the XenU can't be booted, I don't known the critical value,

but I think it is larger then 2G and less then 5G in our server (physical memory is 4G),


when we booted this XenU ,it hanged and  output:


Using IPI Shortcut mode
kjournald starting.  Commit interval 5 seconds
EXT3-fs: mounted filesystem with ordered data mode.
VFS: Mounted root (ext3 filesystem) readonly.
Freeing unused kernel memory: 272k freed


just like there is not enough memory,but we still have 4G mem not used,


and if I use physical partition replace for image file ,


every thing was OK!


any issue?

attached is the xend'log

thanks
Yibin Shen
