if you're running pure pv domUs (with no real hardware support), this should be |
13 |
completely transparent for the hypervisor |
14 |
|
15 |
i'm running x86_64 xen-sources-2.6.34-r5 on both dom0 and domUs on Xen 4.1.2 |
16 |
(still using xend/xm interface): everything works stable enough. i have already |
17 |
switched to new hardware, upgraded xen, kernel configuration and versions whilst |
18 |
domU configs did not change for years |
19 |
|
20 |
the only significant improvement of recent xen (for small configurations: i dont |
21 |
have experience with more than 2 cpu sockets systems) is an enhanced support of |
22 |
vt-d (iommu); turn it off and re-try - there are many incompatibilities there |
23 |
probably causing xen to hang |
