Fwd: Booting physically installed Windows while in Arch (AHCI support in OVMF?)
Please, any help? I'm currently in such a state I won't be able to sleep well before I make some progress on this. I've already described my situation quite precisly, if one needs even more information, just ask. I've now also tried with a separate img containing DUET, so I can use the default seabios to boot DUET, which can boot Windows in UEFI mode. However, DUET just doesn't see my disk at all, be it in IDE or AHCI mode. If I boot the same img *physically* (from a usb), I can enter DUET and I can see my physical disk (which is running in AHCI mode). So I guess this is an issue with KVM/QEMU. Any ideas would be greatly appreciated.

So, I would like to know if OVMF supports AHCI, and if it doesn't, do you have any other ideas? I know it's generally not a good idea to boot a physically installed OS in a vm, but I want to try it anyway.

GUI: convirt or virt-manager?
Hi all, Is any of these 2 better than the other? Or are they both just as good? How do they measure up to the GUI's of VMware/VirtualBox?

Does KVM support this as well? What does this term mean exactly? Is it the same as ballooning used by KVM? I guess it referring to memory allocation on first time access to the memory areas, Meaning the memory allocation will be made only when it really going to be used. Like, two guests, each with 2 GB memory allocated only use 1 GB of host's memory (as long as they don't have many programs/buffers/cache)? So yes, it's also supported by KVM.

KVM + virt-manager: which is the perfect host Linux distro?
Hi all, I am about to install a new host system, which will be hosting various guest systems by means of KVM virt-manager for GUI. What would be the best choice for host OS distro? Red Hat, or will any mature Linux distro do? Personally I am more of a Gentoo guy, but if there is 1 distro which is clearly better as host OS when it comes to KVM+virt-manager, I am willing to use something else... ;-) Regards, Evert -- To unsubscribe from this list: send the line unsubscribe kvm in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

To my knowledge Proxmox does not support software RAID ( http://www.linux-kvm.com/content/kvm-83-released-support-amd-iommu-qemu-svn-merge ), unless you configure that manually... Otherwise Proxmox is promising, yes... Can I conclude from that that Debian is the best host distro to go for? Better than Red Hat Gentoo?

Which SCSI controller is emulated in KVM guests?
Hi all, I must be missing it somehow, but I can't find any mention in the KVM man page on which SCSI controller is emulated in its guests...?
