sorry, I forgot to report the performance of xen4.0+kernel2.6.18.8. xen4.0+kernel2.6.18.8: [ ID] Interval Transfer Bandwidth [ 4] 0.0-16.3 sec 1.79 GBytes 941 Mbits/sec This combination can only meet some of our needs. the reason why we didn't use 2.6.18.8: 1. Our storage application is base on NBD, which will goto deadlock on 2.6.18.8 when nbd-client and nbd-server are deployed on the same server. 2. Hard disk frequently offline so we want to upgrade to kernel2.6.31. we also try xen4.0+kernel2.6.31.12(gentoo-xen-kernel patch). the performance is acceptable, but blktap2(support VHD) not work. has anybody solve the problem in xen4.0+kernel2.6.31.13?
