I run Xen 4.6 Dom0
rpm -qa | egrep -i "kernel-default-4|xen-4"
kernel-default-devel-4.4.0-8.1.g9f68b90.x86_64
xen-4.6.0_08-405.1.x86_64
My guests are currently HVM in PVHVM mode; I'm exploring PVH.
IIUC, for 4.6, this doc
http://xenbits.xen.org/docs/4.6-testing/misc/pvh-readme.txt
instructs the following necessary changes:
@ GRUBG cfg
- GRUB_CMDLINE_XEN=" ..."
+ GRUB_CMDLINE_XEN=" dom0pvh ..."
&, @ guest.cfg
+ pvh = 1
For my guest.cfg, currently in PVHVM mode, I have
builder = 'hvm'
xen_platform_pci = 1
device_model_version="qemu-xen"
hap = 1
...
Q:
Do any of these^^ params need to also change with the addition of
pvh = 1
> At the moment HAP is required for PVH.
As above, I've 'hap = 1' enabled.
But checking cpu,
hwinfo --cpu | egrep "Arch|Model"
Arch: X86-64
Model: 6.60.3 "Intel(R) Xeon(R) CPU E3-1220 v3 @ 3.10GHz"
neither 'hap' nor 'emt' are specifically called out,
egrep -wo 'vmx|lm|aes' /proc/cpuinfo | sort | uniq \
| sed -e 's/aes/Hardware encryption=Yes (&)/g' \
-e 's/lm/64 bit cpu=Yes (&)/g' -e 's/vmx/Intel hardware
virtualization=Yes (&)/g'
Hardware encryption=Yes (aes)
64 bit cpu=Yes (lm)
egrep -wo 'hap|vmx|ept|vpid|npt|tpr_shadow|flexpriority|vnmi|lm|aes'
/proc/cpuinfo | sort | uniq
aes
lm
Iiuc, Intel introduced EPT with Nehalem arch, which preceds Haswell by ~
5 years.
Q:
Am I out of luck re: PVH with more modern Haswell? Or is there a
different check I should be running ?
> At present the only PVH guest is an x86 64bit PV linux.
Is this still current/true info?

Hm, maybe you haven't realized, but the content in (1) and (2) it's exactly the same.

Roger. This actually never happened for Linux: HVMlite showed up fast enough that it didn't make sense anymore to add 32-bit support to Linux (especially given that AMD was still not supported). -boris ^ permalink raw reply [flat|nested] 27+ messages in thread

If that's a 'done deal', and it sounds like it is, it'd be useful to have it integrated into: http://wiki.xen.org/wiki/Understanding_the_Virtualization_Spectrum particularly as there's no mention of HVMlite on the wiki, at all. It's unclear whether PVH, in its current dev state (at least here), is worth-the-visit -- especially if HVMlite is "ComingSoon(tm)". I suppose I'm looking for some guidance as to which to invest time in while on Xen 4.6.0, ack'ing that neither PVH nor HVMlite are production-ready. ^ permalink raw reply [flat|nested] 27+ messages in thread

HVMlite is very new: domU hypervisor support has been added less than two months ago and Linux patches are being reviewed as we speak (FreeBSD, I believe, is supported). > > It's unclear whether PVH, in its current dev state (at least here), is > worth-the-visit -- especially if HVMlite is "ComingSoon(tm)". > > I suppose I'm looking for some guidance as to which to invest time in > while on Xen 4.6.0, ack'ing that neither PVH nor HVMlite are > production-ready. Current PVH implementation has never been described as production-ready. What is happening now with HVMlite is essentially bringing PVH to production-quality level. -boris ^ permalink raw reply [flat|nested] 27+ messages in thread

I created the Xen modes diagram on this page (based on the older modes diagram; if anyone wants the new omnigraffle source, email me), and I just created a Xen wiki account so I can update this page. I've been meaning to update this modes diagram anyway, and improve the columns. > HVMlite is very new: domU hypervisor support has been added less than two > months ago and Linux patches are being reviewed as we speak (FreeBSD, I > believe, is supported). > > >> It's unclear whether PVH, in its current dev state (at least here), is >> worth-the-visit -- especially if HVMlite is "ComingSoon(tm)". >> >> I suppose I'm looking for some guidance as to which to invest time in >> while on Xen 4.6.0, ack'ing that neither PVH nor HVMlite are >> production-ready. >> > > Current PVH implementation has never been described as production-ready. > What is happening now with HVMlite is essentially bringing PVH to > production-quality level.

I am not sure it should be classified as PV mode anymore since it's really an HVM guest without any devices. But it's not there yet so it's too early to point your editor there. BTW, I don't think the flowchart in the wiki is correct as far as PVH is concerned --- you can't use PVH unless HVM (and, in fact, PVHVM) is supported. -boris > Or too much of a simlification? thanks, ^ permalink raw reply [flat|nested] 27+ messages in thread

Noting the very recent flurry of HVMLite activity, so where does PVH sit? As it's not production-ready (and, atm, unusable here), is it planned to be?
