ConoHa 上で必要な Linux Kernel 設定
ConoHa に Gentooを導入するときのメモ。
デバイス情報
lspci は以下の通り。普通の440FXエミュレートなので、基本的には virtio さえ気にすればよい。
livecd ~ # lspci
00:00.0 Host bridge: Intel Corporation 440FX - 82441FX PMC [Natoma] (rev 02)

00:01.2 USB controller: Intel Corporation 82371SB PIIX3 USB [Natoma/Triton II] (rev 01)
00:01.3 Bridge: Intel Corporation 82371AB/EB/MB PIIX4 ACPI (rev 03)

00:05.0 SCSI storage controller: Red Hat, Inc Virtio block device
00:06.0 Unclassified device [00ff]: Red Hat, Inc Virtio memory balloon
cpuinfo は以下の通り。今回のインスタンスは IvyBridge らしい。
livecd ~ # cat /proc/cpuinfo

genkernelでの注意
最近は genkernel --virtio がうまくいかない時がある。
livecd ~ # genkernel --virtio all
<snip>

というより、genkernel --virtio はだいぶ古いようで色々おかしい。
素直に手動で以下を組み込もう。
要組み込み箇所
Device Drivers --->
Virtio drivers --->
<*> PCI driver for virtio devices
<*> Virtio balloon driver
<*> Platform bus driver for memory mapped virtio devices
[*] Block devices --->
<*> Virtio block driver
-*- Network device support --->
[*] Network core driver support
<*> Virtio network driver
Character devices --->
<*> Virtio console
<*> Hardware Random Number Generator Core support --->
<*> VirtIO Random Number Generator support
Device Drivers --->
Virtio drivers --->
<*> PCI driver for virtio devices
<*> Virtio balloon driver
<*> Platform bus driver for memory mapped virtio devices
[*] Block devices --->
<*> Virtio block driver
-*- Network device support --->
[*] Network core driver support
<*> Virtio network driver
Character devices --->
<*> Virtio console
<*> Hardware Random Number Generator Core support --->
<*> VirtIO Random Number Generator support
これで一通りは問題ないはず。
VirtIO Random Number Generator は不要かもしれない(lspci上は出てこないし)。
