Re: [Xen-devel] TESTDAY report 4.11rc6

[pierre-philipp braun <pbraun@xxxxxxxxxxxx>]

Hello.  Some update on my 4.11rc6 tests.  In brief, Linux guest
migration works fine.  Some issues with NetBSD guests' migrations but
this is not necessarily related to 4.11rc6.  I am rather addressing this
to the port-xen netbsd mailing-list.

In detail, I am maintaining a farm of 4 XEN hosts running Linux dom0s:

HARDWARE
ubuntu1:        Product Name: IBM 3850 M2 / x3950 M2 -[71414RG]-
slack2 :        Product Name: IBM 3850 M2 / x3950 M2 -[71414RG]-
slack3 :        Product Name: IBM 3850 M2 / x3950 M2 -[71414RG]-
slack4 :        Product Name: IBM 3850 M2 / x3950 M2 -[71414RG]-

XEN VERSIONS
ubuntu1: (XEN) Xen version 4.9.0 (Ubuntu 4.9.0-0ubuntu3)
(stefan.bader@xxxxxxxxxxxxx)
slack2 : (XEN) Xen version 4.11-rc (root@example.local)
slack3 : (XEN) Xen version 4.11-rc (root@example.local)
slack4 : (XEN) Xen version 4.11-rc (root@example.local)

LINUX VERSIONS
ubuntu1: 4.13.0-39-generic
slack2 : 4.17.1.slackxen
slack3 : 4.17.1.slackxen
slack4 : 4.4.88.xen

XEN GUESTS
PV teacher: Ubuntu artful 17.10 with vmlinuz-4.13.0-21-generic kernel
and Blktap2 tap:qcow2 against a virtual disk
PV ubuntustrap1: Ubuntu artful 17.10 with custom vmlinuz.4.4.88.domu
kernel and Blktap2 tap:tapdisk:aio against a virtual ext4 disk/partition
PV snegw: NetBSD 7.1.2 (XEN3_DOMU.201803151611Z) using Blktap2 tap:qcow2
against a virtual disk
PV netbsdffs8: NetBSD 8.0_RC1 (XEN3_DOMU.201804191727Z) using Blktap2
tap:tapdisk:aio against a virtual ffs disk/partition

LINUX GUEST MIGRATION TESTS
- both the teacher and ubuntustrap1 guests hot-migrate fine from
ubuntu1->slack2->slack3->slack4 and back to ubuntu1

NETBSD GUEST MIGRATION TESTS
- migrating snegw from slack3 to slack4 succeeds but prints an error
- migrating snegw from slack4 to slack3 fails
- migrating netbsdffs8 from slack3 to slack4 fails
- migrating netbsdffs8 from slack4 to slack3 fails
