[one-users] Windows Instalaltion

[Carlo Daffara]

If you use KVM as the hypervisor, there is a known issue where the I/O emulation is substantially slowed by the continuous fsync that the installer performs.
The fastest solution is to apply the property CACHE="UNSAFE" to the disk where windows is installed, and change it later (either deleting it, using "DEFAULT" or one of the
other cache modes supported by KVM). This will force KVM to ignore the continuous read/write/check that is performed sector by sector and will speed it up substantially the
process.
Remember to change it later- there is a reason why the mode is called unsafe... it should be used only for this specific purposes and not in production.

Oggetto: [one-users] Windows Instalaltion



Hello, 



I have a problem when I create a WINDOWS virtual machine from iso in Sunstone . 

I attach a pic. 

The installation process hangs at that point and doesn’t continue. 



Thank you!
