Hi,

 

Newbie question…

 

I want to enable IOMMU in XCP 1.6.  I’ve done some searching and I’ve found numerous entries where you simply add ‘iommu=1’ as a kernel boot option.  However I can’t seem to find out how to do that with XCP 1.6 given grub is not installed.

 

[root@vmhost /]# dmesg | grep -i 'command'

[    0.000000] Kernel command line: root=LABEL=root-ktayzycm ro xencons=hvc console=hvc0 console=tty0 quiet vga=785 splash

 

So how do I add ‘iommu=1’ to the Kernel command line in XCP 1.6?

 

Thanks

Micah
