To test if EPT is enabled on my machine, I add some codes in my own xen shadow
and create a guest vm (named testvm) by Virtual Machine Manager. However, it
seems that testvm doesn''t use EPT at all (See the log). So how to turn
on EPT support? I thought it should be enabled automatically.
My box is configured as:
Intel Core i7 965
2G*3 DDR3 1333
Seagate 1T

Can you check Xen''s boot log to see whether the sentence as following
is printed out ?
(XEN) HVM: Hardware Assisted Paging detected.
I don''t know Xen-3.4.2''s policy for EPT''s default
option, maybe you can add "hap=1" in your configuration file to ensure
EPT on when you create virtual machine if the system supports it.

Those flags are passed from the domain-builder tools in dom0 (xc_domain_create() in tools/libxc/xc_domain.c). If you''re using xend, it looks like those flags get assembled from magic numbers in XendDomainInfo.py based on one of the many config objects. Try adding ''hap=1'' to your xm config file?

i7 965 has EPT support.
Use command "xm debug-k v; xm dmesg" to see if EPT pointer is 0. If 0
then EPT should disabled for the guest.
as Xiantao mentioned, I guess your hap in config file is set to 0. By default if
you don''t set it, ept should be enabled.

Thanks. I tailor the hvm example configuration file in xen manually instead of
using Virtual Machine Manager. I use your method to verify it and the problem is
solved now.
However I find that hap configuration belongs to the Timers category in Xen
Configurations Details
(http://www.xen.org/files/Support/XenConfigurationDetails.pdf), is it a mistake?

Subject: [Xen-devel] How to turn on EPT support?
To test if EPT is enabled on my machine, I add some codes in my own xen shadow
and create a guest vm (named testvm) by Virtual Machine Manager. However, it
seems that testvm doesn''t use EPT at all (See the log). So how to turn
on EPT support? I thought it should be enabled automatically.
My box is configured as:
Intel Core i7 965
2G*3 DDR3 1333
Seagate 1T
Centos 5.2
Xen-3.4.2 with linux 2.6.18 xenified kernel (downloaded from xen.org)
