Some of the changes and new features introduced with version 3.4.2:

  • Support for NVM Express (NVMe) devices:
    • Discover NVMe devices and present them to Oracle VM Manager
    • NVMe devices can be used to store virtual machine disks or create storage repositories
  • Extended SCSI functionality available for virtual machines
    • Linux guests can now retrieve vital product data (VPD) page 0×84 information from physical disks if the device itself makes it available.
  • The management domain (dom0) kernel upgraded to Oracle Unbreakable Enterprise Kernel Release 4 Update 2 (4.1.12-61.1.9)
  • The Xen hypervisor performance and scalability updates:
    • Improved memory allocation
    • Improved aggregate performance
    • Improved performance for Windows, Solaris and Linux guests
    • Improved workload performance
    • Guest disk I/O performance improvements
  • Oracle VM Manager performance enhancements - improved performance under heavy event load
  • Oracle VM Manager Rule for Live Migration - blocks unsupported Live Migration paths
  • Hot memory modification for HVM guests with para-virtualized I/O drivers (PVHVM) - modify the memory allocated to running PVM guests as well as PVHVM guests without a reboot.
  • Package additions and updates
  • Security updates for the embedded components of Oracle VM Server and Oracle VM Manager.

Recovery Checkpoint

Hi,

Host: Windows 2012 R2
VM:   Windows 2012 R2
Storage: Direct Attached (Dell PowerVault MD3400)

I have a VM that is used as a productionFile Server.  This has a number of vhdx’s (C: OS, D: Data Y: Pagefile and a 10TB Shares disk that is mounted to a folder in D:).

Recently a backup (Altaro) has created a recovery checkpoint and failed (31st August). Consequently the checkpoint file never got deleted and therefore I have a number of avhdx’s.  In Hyper-V Manager there is no option to to Delete or Delete the Subtree. 
Also there have been no backups since this date as another (inconsequential) VM suffered the same fate and backups just kept creating new recovery checkpoints.

Running Get-VMSnapshot -VMName hstv.artemis gives this.

VMName       Name                                           
SnapshotType CreationTime        ParentSnapshotName

——       —-                                           
———— ————        ——————

hstv.artemis hstv.artemis - Backup - (31/08/2016 - 16:39:31) Recovery     31/08/2016 16:41:33

Trying Get-VMSnapshot -VMName hstv.artemis | Remove-VMSnapshot fails with (Cannot delete checkpoint: Catastrophic failure (0x8000FFFF).

My research indicates my only option is to do an offline manual merge (on copies) of the disks to get them all back into single vhdx’s.

  1. Is this my only option?
  2. What would happen to the VM Snapshot files?

Thanks
Tony

Manage Server 2012 R2 Hyper-V from Win 10 LTSB 2016 client = "…could not access an expected WMI class…"

Trying to access Hyper-V running on Server 2012 R2 from Windows 10 LTSB 2016 and I only get an error:

The Hyper-V Management Tools could not access an expected WMI class on computer….

Same server accessed from Windows 8.1 H-V Management Tools is working fine.

Anybody any idea?

According to
this
it should be no issue

VMworld US 2016 Wrap-up

Read full post . . . or http://feedproxy.google.com/~r/Virtualization_info/~3/G9Iyw-fdTbQ/vmworld-us-2016-wrap-up.html

Today was the last day of VMware’s flagship conference VMworld in Las Vegas, an highly controversial edition which left a good chunk of the audience disoriented if not properly disappointed.

The debate started during Day 1 Keynote and then proliferated over Twitter in various strands. Part of the audience commented that the message delivered during the keynote suggests developers and cloud-native applications (delegated to Day 2 Keynote) as second-class citizens in VMware’s world.

Others complained that the announcements of VMware Cloud Foundation and Cross-Cloud Services (moreover in technical preview) are too few and too late to amend the One Cloud mantra VMware has drummed for an entire year.

Anyway each of these (legit) comments has been addressed by the vast legion of VMware’s aficionados and you can enjoy the discussion on Twitter with the hashtag #VMworld and form your own opinion.

Criticism hasn’t ruined the party and here is a compendium of the announcements that followed:
