Public bug reported: Hi,
Applying the Spectre/Meltdown patched kernel (3.2.0-133-generic - precise ESM), it's not possible to boot my xen domUs anymore (dom0 is fine). It works fine with 3.2.0-131-generic and 3.13.0-141-generic (lts- trusty with Spectre/Meltdown mitigations). This is with xen 4.1.6.1-0ubuntu0.12.04.13 xend.log below : [2018-02-22 10:56:03 1566] DEBUG (XendDomainInfo:103) XendDomainInfo.create(['vm', ['name', 'REDACTED'], ['memory', '6144'], ['on_reboot', 'restart'], ['on_crash', 'destroy'], ['on_xend_start', 'ignore'], ['on_xend_stop', 'ignore'], ['vcpus', '1'], ['oos', 1], ['image', ['linux', ['kernel', '/vmlinuz'], ['ramdisk', '/initrd.img'], ['root', '/dev/xvda1 ro'], ['videoram', 4], ['args', 'nogbpages console=hvc0 earlyprintk=xen nosplash'], ['tsc_mode', 0], ['nomigrate', 0]]], ['s3_integrity', 1], ['device', ['vbd', ['uname', 'phy:/dev/Ubuntu/REDACTED-disk'], ['dev', 'xvda1'], ['mode', 'w']]], ['device', ['vbd', ['uname', 'phy:Ubuntu/REDACTED-swap'], ['dev', 'xvda2'], ['mode', 'w']]], ['device', ['vif', ['ip', 'REDACTED'], ['mac', '02:00:5B:BD:5E:E2']]]]) [2018-02-22 10:56:03 1566] DEBUG (XendDomainInfo:2498) XendDomainInfo.constructDomain [2018-02-22 10:56:03 1566] DEBUG (balloon:187) Balloon: 6291628 KiB free; need 16384; done.
