cwc,
I use KVM / QEMU with virt-manager for linux on linux unless it a quick throw away VM, then its VBox.
Windows guests count as quick throwaways :)
In practice, I never throw anything away. so I have to keep getting bigger HDDs every time I get a new PC :) _________________ Regards,

thanks for the input Neddy
excellent
"KVM / QEMU with virt-manager"
The following should get me started:
https://wiki.gentoo.org/wiki/QEMU
Enable KVM Support (CONFIG_KVM)

cwc,
If you want to use virtio devices, both the host and guest kernels need to be able to support virtio.
To run unmodified guests, QEMU will offer the guests some emulated hardware.
virtio is preferred as is does away with the emulated hardware overhead.
I use KVM / QEMU with virt-manager on both arm64 and amd64 _________________ Regards,

Neddy,
Why a module rather than a kernel build in?
KERNEL Enable KVM support for Intel processors (CONFIG_KVM_INTEL)
[*] Virtualization --->
<M> KVM for Intel processors support
I'm using an intel i7 _________________ Without diversity there can be no evolution:) |

Thanks Neddy
"CONFIG_KVM_INTEL=y"
this is mine
more .config | grep CONFIG_KVM_INTEL
CONFIG_KVM_INTEL=m
I'll update and recompile.
I can not find <*> Mediated device driver framework

I instilled QEMU after following the the kernel guide.
https://wiki.gentoo.org/wiki/QEMU
These are the libvirt notifications I recieved:
Code: |
* Messages for package app-emulation/libvirt-9.8.0-r2:
* CONFIG_BRIDGE_EBT_MARK_T: is not set when it should be.
* CONFIG_BRIDGE_NF_EBTABLES: is not set when it should be.
* CONFIG_NETFILTER_ADVANCED: is not set when it should be.
* CONFIG_NETFILTER_XT_CONNMARK: is not set when it should be.
* CONFIG_NETFILTER_XT_TARGET_CHECKSUM: is not set when it should be.
* CONFIG_IP6_NF_NAT: is not set when it should be.
* CONFIG_BRIDGE_EBT_T_NAT: is not set when it should be.
* CONFIG_NET_ACT_POLICE: is not set when it should be.
* CONFIG_NET_CLS_FW: is not set when it should be.
* CONFIG_NET_CLS_U32: is not set when it should be.
* CONFIG_NET_SCH_HTB: is not set when it should be.

You do not need libvirt to use qemu. I do not have libvirt on the system where I run qemu.
The notifications are telling you about kernel configuration options that are required for certain aspects of the hypervisor to work properly. Depending on what you want to do with the guest, you may or may not need to resolve any or all of these. If you encounter any networking problems with the guest, I would suspect these absences first. If you do not encounter problems, you could choose to ignore these warnings. |

equery d libvirt
* These packages depend on libvirt:
app-emulation/libvirt-9.8.0-r2 (policykit ? acct-group/libvirt)
app-emulation/libvirt-glib-4.0.0 (>=app-emulation/libvirt-1.2.
dev-python/libvirt-python-9.8.0 (app-emulation/libvirt:0/9.8.0)
(test ? app-emulation/libvirt:0/9.8.0)
virt-manager pulled libvirt (I think)
Code: |
emerge virt-manager
The following USE changes are necessary to proceed:
(see "package.use" in the portage(5) man page for more details)
# required by app-emulation/virt-manager-4.1.0-r1::gentoo[-test,gui]
# required by app-emulation/virt-manager (argument)
>=net-misc/spice-gtk-0.42-r3 usbredir

# required by app-emulation/libvirt-glib-4.0.0::gentoo
# required by app-emulation/virt-manager-4.1.0-r1::gentoo[-test]
# required by app-emulation/virt-manager (argument)
>=net-dns/dnsmasq-2.90 script

I need to look what pulled it. |

I start qemu from the command line. Usually, I have a helper script that memorizes my standard options for a VM, so I don't need to retype them all every time. |

thank you Hu. I'll try to work on that

Code: |
qemu-
qemu-edid qemu-io qemu-pr-helper qemu-system-arm qemu-system-x86_64

I've always used cmdline qemu, libvirt is probably easier for a newbie.
But anything done in libvirt can be done from the cmd line.
I made a little dialog script, that allows me to choose which vm to start.
Code: | $DIALOG --title "Qemu Virtual Machines" --clear \
--radiolist "Select?" 45 65 8 \
"0" "Choose ISO" off \
"1" "Choose Linux Distro" off \
"2" "W98se" off \
"3" "XP" off \
"4" "W7" on \
"5" "W8.1" off \
"6" "W11" off 2> $tempfile |
I use taskset to pin certain core/threads for the vm, something libvirt does also.
You learn more about virtual machines using qemu from the cmdlilne, but it's up to you. _________________ PRIME x570-pro, 3700x, 6.1 zen kernel

I am going to start over from scratch.
I'll use my old kernel .config and start from scratch.
Thank you for all the input.
I've learned a lot!
This is such a wonderful forum . I'm a retired Comp Sci instructor and my gentoo machines are so much fun and challenging at the same time.
Thank again! _________________ Without diversity there can be no evolution:) |
