Adding Daniel & Jan. Looking at the most recently failed flight http://www.chiark.greenend.org.uk/~xensrcts/logs/15046/test-amd64-i386-xl-win-vcpus1/info.html we have http://www.chiark.greenend.org.uk/~xensrcts/logs/15046/test-amd64-i386-xl-win-vcpus1/8.ts-guest-saverestore.log which contains: Loading new save file image (new xl fmt info 0x0/0x0/620) Savefile contains xl domain config WARNING: ignoring "kernel" directive for HVM guest. Use "firmware_override" instead if you really want a non-default firmware xc: error: panic: xc_dom_boot.c:410: xc_dom_gnttab_hvm_seed: failed to remove gnttab from physmap [errno=2] : Internal error xc: error: error seeding grant table: Internal error libxl: error: libxl_create.c:787:libxl__xc_domain_restore_done: restoring domain: Resource temporarily unavailable libxl: error: libxl_create.c:869:domcreate_rebuild_done: cannot (re-)build domain: -3 libxl: error: libxl.c:1377:libxl__destroy_domid: non-existant domain 5 libxl: error: libxl.c:1341:domain_destroy_callback: unable to destroy guest with domid 5 libxl: error: libxl_create.c:1175:domcreate_destruction_cb: unable to destroy domain 5 following failed creation Parsing config from /etc/xen/win.guest.osstest.cfg Which is the same as the bisection result here http://www.chiark.greenend.org.uk/~xensrcts/logs/15054/test-amd64-i386-xl-win-vcpus1/8.ts-guest-saverestore.log I've eye balled 26350:ba386fd2bf17, especially the bits about the phsymap hypercalls and I can't see anything obvious.
