Hello, I am running r271243 I just installed a Ubuntu 14.04.1 server guest which went fine. After updating the system with "apt-get dist-upgrade" and rebooting, the VM does not complete the boot process. The last few lines displayed are: [ 0.002359] Dentry cache hash table entries: 131072 (order: 8, 1048576 bytes) [ 0.003757] Inode-cache hash table entries: 65536 (order: 7, 524288 bytes) [ 0.004731] Mount-cache hash table entries: 2048 (order: 2, 16384 bytes) [ 0.005267] Mountpoint-cache hash table entries: 2048 (order: 2, 16384 bytes) [ 0.006128] Initializing cgroup subsys memory [ 0.006493] Initializing cgroup subsys devices [ 0.006859] Initializing cgroup subsys freezer [ 0.007226] Initializing cgroup subsys blkio [ 0.007579] Initializing cgroup subsys perf_event [ 0.007966] Initializing cgroup subsys hugetlb [ 0.008665] Last level iTLB entries: 4KB 512, 2MB 0, 4MB 0 [ 0.008665] Last level dTLB entries: 4KB 512, 2MB 32, 4MB 32 [ 0.008665] tlb_flushall_shift: 2 [ 0.010121] Freeing SMP alternatives memory: 32K (ffffffff81e6e000 - ffffffff81e76000) [ 0.014325] ACPI: Core revision 20131115 [ 0.014888] ACPI: All ACPI Tables successfully acquired [ 0.015391] ftrace: allocating 28541 entries in 112 pages [ 0.048623] smpboot: CPU0: Intel(R) Xeon(R) CPU E3-1230 V2 @ 3.30GHz (fam: 06, model: 3a, stepping: 09) Does anyone know what is preventing the VM from booting successfully?
