SCVMM 2008 - cannot remove missing VM

When you see in SCVMM Virtual Machine status "missing", it means scvmm sql db is corrupted, most probably due to cluster mis-operation.

Try to start migrate VM on another host. When you see the duplicate VM and one of them running correctly, then you may remove mising VMs:;EN-US;983839

The state "missing" has a code 220, and "update failed" 107. You may need to modify script, since the code is hardcoded there:

dbo.tbl_WLC_VObject WHERE [ObjectState] = 220
dbo.tbl_WLC_VObject WHERE [ObjectState] = 107

Xen editions differences

XenDesktop editions:

Windows VDA license

Microsoft® has announced the following licensing changes for virtual desktops that will come into effect on July 1st, 2010:
• Windows® Virtual Enterprise Centralized Desktop (Windows VECD) and Windows VECD for Software Assurance (SA) will no longer appear on the price list.
• Virtual desktop access rights will become a Windows Client Software Assurance benefit. Customers who intend on using PCs covered under SA will now be able to access their Virtual Desktop Infrastructure (VDI) desktops at no additional charge.
• Customers who want to use devices such as thin clients that do not qualify for Windows Client SA would need to license those devices with a new license called Windows Virtual Desktop Access (Windows VDA) to be able to access a Windows VDI desktop. Windows VDA is also applicable to third party devices, such as contractor or employee-owned PCs.

Spent few moments trying to figure out why server's giga NIC sets to 100MB only... Twicked cisco switch port, restarted interface few times, even tried different distro - ubuntu instead of centos - result zero! Finally went and changed a patch cable - surprise-surpise: 1GB! IT is used to blame OS or driver, but HW is equally important...
