I've been testing kvm for couple of months with the following hardware : S5000pal intel board 1x Duo Core Xeon 2.4 2048Gb DDR2 667 Ram Western digital SATA 150 10K rpm disk. I run kvm21 at the moment...(I need to upgrade asap of course ;) ) And have the following questions : 1* When i run hdparm -t /dev/sda1 I have 80-85Mbit/s read speed on my guest os (debian etch) If I run it ''in'' a virtual machine (using also debian Etch with 2.6.21.5 kernel) I get : 28-35Mbits... I even tried to put the image on a seperate disk to be able to have more, but I can't get more then 35Mbits out of it... How can I up the disk performance without having to replace everything by SCSI hardware ? 2* When will smp be supported in the VM ? Would love to test the performance by starting up the virtual machine with the -smp 2 command...Kernel hangs at the moment (I read you guys put it on the commit list, and you're working on it...) 3* When I specify a mac address for my debian virtual machine eth0 changes to eth3 ... very very weird... it's not that bad, i just changed my interfaces config file from eth0 to eth3, but it's a bit weird My windows xp seems to boot without a problem when specifying another mac addr Did you guys have that problem yet ? How can I fix it please ? Keep up the good work, lovely product ! thx Ben ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
