[Xen-devel] Testing status of fully virtualized guests (Intel VT) on 32bit XEN unstable

Test Configuration:
Dell PowerEdge 430, Dual Core, 2GB, 3 SATA (Intel VT)
32bit XEN Hypervisor on a RHEL4U2 32bit root (/dev/sda)
       dom0_mem=256M (required to boot domUs)
32bit fully virtualized (HVM) guest RHEL4U2 256MB (/dev/sdb)
       pae=1, acpi=1, apic=1
       kernargs clock=pit
32bit fully virtualized (HVM) guest RHEL3U6 256MB (/dev/sdc)
       pae=1, acpi=1, apic=1
       kernargs clock=pit

Boot Tests:
Boot a fully virtualized (HVM) guest to the login prompt
Results are marked Pass|Fail where (n) points to a failure description

Regression Tests:
851 tests (850 ltp tests and one 30 minute user load test)
Tests are marked #Pass/#Fail where (n) points to a failure description

RE: [Xen-devel] Testing status of fully virtualized guests (Intel VT) on 32bit XEN unstable

Hi, Ed Smith

Thank you very much for the testing!!

For ia32 testing you should not enable pae=1 in the config.
Ia32-pae guest should not be able to boot on ia32 hypervisor.
Currently it can only work on ia32e hypervisor.
The smp kernel of RHEL4U2 is pae enabled.
This is the reason why you failed to boot smp ia32 guest.
If you want to boot a smp kernel on ia32 hypervisor, you should make the kernel
by yourself and disable pae in the kernel config.

Thanks

[Xen-devel] Testing status of fully virtualized guests (Intel VT) on 32bit XEN unstable

RE: [Xen-devel] Testing status of fully virtualized guests (Intel VT) on 32bit XEN unstable

Thanks for your help.  I tried building 32bit XEN with XEN_TARGET_X86_PAE=y and
then tried booting RHEL4U2 SMP (pae=1) and see the same hang so I do not think
this is necessarily the reason I''m failing.  Although I realize if I
was able to get by the hang I''d likely fail elsewhere trying to boot a
PAE kernel on a non-PAE hypervisor.

I see the same domU hang after the "Uncompressing Linux... Ok, booting the
kernel." message on both RHEL4U2 and RHEL3U6 SMP guests on either 32bit
XEN, 32bit PAE XEN or 64bit XEN hypervisors.  The uni-processor guest kernels
boot fine.  It would seem booting a 32 SMP kernel (HVM) on any hypervisor is not
quite working yet.

Ed

Hi, Ed Smith

Thank you very much for the testing!!

For ia32 testing you should not enable pae=1 in the config.
Ia32-pae guest should not be able to boot on ia32 hypervisor.
Currently it can only work on ia32e hypervisor.
The smp kernel of RHEL4U2 is pae enabled.
This is the reason why you failed to boot smp ia32 guest.
If you want to boot a smp kernel on ia32 hypervisor, you should make the kernel
by yourself and disable pae in the kernel config.

Thanks

We''ve seen this, and is one of the factors driving the push for
a new device model for fully virtualized guests. I''m not sure if
anyone is looking into shorter term investigation/hacks for it
or taking 2.4 based guests very seriously at this point.

thanks,
Nivedita

    on RHEL3U6-32b while it take 4 minutes on RHEL4U2-32b.
