boot linux2.6 in virtual machine

[horseriver]

hi:)
  
  I have compiled a kernel of 2.6 version . there is an bzImage file generated and I 
  have got a initrd.img file here.
  Now ,I want to boot  this kernel , Need I have a boot-loader ? Is GRUB right for this?
  Need I mount kernel image and initrd.img on /dev/XXX ?  If need, when to do mount them?


thanks!
