Correct - It is the 4.4 Hypervisor with 4.5 toolstack. After a reboot, all is good. However this causes the problem - once you update the packages from 4.4 -> 4.5, you lose the ability to manage any running DomU= s. This is problematic - if only for the fact that you can't shut down running DomUs for the Dom0 reboot. I understand that large jumps in versions isn't supported - but I believe that point versions should be supported using the same toolset. ie 4.2 -> 4.3, 4.4 -> 4.5 etc. I'm just about to gather some data for it - and I'll make a new thread with what I can gather. --=20 Steven Haigh Email: netwiz@crc.id.au Web: http://www.crc.id.au Phone: (03) 9001 6090 - 0412 935 897 --tnN6VxPKRVWJ4iJ258kl1rx6u4U70uFtX Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBAgAGBQJU2HlMAAoJEEGvNdV6fTHcX/gP/ijgrn5uodnvc+6NLIGR/x54 s9Iz3nySCZ0UXHt8ZaiVZDzKgNQnCOme4aBMWusTmi/T3Yrcz0IfqW2D+Plo/36U SgfwoXJ4zwLDs89XtbDBim5ZsXVpO8nX48m0v9e+atOjTKOkJ8yKXsZoqyjJy+dq cPLM/Fl2VOmkf08Zi+Np584W/nYR75ALwfxC3UH1uYCHuLyI3UKwR0ru3kyWgo2w HrNAA1Ibw0n1bcSKckO+1tZHdBGVTxqKoJ4+fLbeuzHGGWAGtSUC1SsXzr/g/Ko/ xifH4sNxYUZD30EhRl3wVB+UET8AyUkgp+bpcJ+JGfwCJQhiwz0tRTyzgJ8MYccE X0y97JfDKDFdNP4rwrSK7yILGCFgiWZPcLEoMAxTM/gFluzZQ4arGlaYtOAHKcVU WXFGHYfRSOco1ku1eAzhQXnZtFN6/eRh1FjhiChFtb4e34lr3b4caL77/qKRXUif QFCBVAoAI4vRomh30Don/GVBGEK2iHDUXbZO2QVbHHC2oYsulIVs0VpD1pC8F5FI Y8DHR2g+bxSfSzJMhM5eyKc975SuES42uZQZUluqJEzCg7c7/gBI5zDsaNzW1PoN UxgIP9qVrBYu3Wl6oEC21EwcNVaOAF+OyAU4xLrO8unzqf0Eortex704iLRIKS6B W7NMlkZsR7tpaApiQTV6 =JGb2 -----END PGP SIGNATURE----- --tnN6VxPKRVWJ4iJ258kl1rx6u4U70uFtX-- --===============5371370207314175500== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel --===============5371370207314175500==--
