[Xen-ia64-devel] [Question] Which feature of Xen-IPF will reserve much memory of a VTI guest?

["Zhang, Jingke" <jingke.zhang@xxxxxxxxx>]

Hi all,
    When we check the "/proc/meminfo" in the VTI, we found the total
memory is about 100MB less than what we config. For x86_64 and KVM side,
they are different. So, I want to ask a question: Is there any feature
reserving much memory of VTI? Thank you very much!

    BTW, by command "dmesg | grep reserve":
    For RHEL4u4 VTI ------ Memory: 942976k/1018784k available (5714k
code, 87712k reserved, 2279k data, 384k init)    
    For RHEL4u4 x86_64 VMX ------ Memory: 1024844k/1048544k available
(2105k kernel code, 0k reserved, 1297k data, 196k init)
    For RHEL4u4 x86_64 KVM ------ Memory: 1024772k/1048512k available
(2105k kernel code, 0k reserved, 1297k data, 196k init)


Thanks,
Zhang Jingke
