Re: [gentoo-user] VMs - what technology would you advise?
I would suggest QEMU/KVM takes the place of VirtualBox. I've not actually found anything it doesn't support, though VirtualBox is far more polished. Starting a VM will be as easy as running a shell script (or you can use virt-manager).

For simple tests where you only briefly run the VM on a desktop/workstation/laptop, VirtualBox generally does the trick. If you actually need to run the VMs for longer periods of time, having a dedicated machine running the likes of Xen or VMWare is a better option. Of the 2, I would recommend Xen. If you don't feel like configuring the whole stack yourself, a pre-build image like "XCP" generally does the trick. This is a free version of the Citrix VM product. The Citrix VM manager works with XCP as well. -- Joost

You have a working solution that does everything you need it to do and it's familiar to you. I'm not seeing any good reason to change it, unless you feel like playing with new toys, but that's never a good reason to change something in production. If you often create new VMs with different configuration and it's becoming a pain setting them all up anew each time, look into vagrant/docker/ansible for ways to automate that process.

[gentoo-user] VMs - what technology would you advise?
For years now I have been running VirtualBox for testing purposes. It has served the users' needs well, but I have set up a new PC and am wondering if I am missing out on new tricks. The VMs are launched may be a couple of times a week for an hour or two, to test website designs on different OS' and browsers. The Vbox does this flawlessly. Is there a different technology and applications I should consider and how do these compare with Vbox? -- Regards, Mick signature.asc Description: This is a digitally signed message part.

Most of the benefits come from avoiding disk operations. If you write 1 byte to the middle of a file ext4 will overwrite one block in-place, and md will read a stripe and then rewrite the stripe. If you write 1 byte to the middle of a file on btrfs (and likely zfs) it will just write 1 byte to the metadata and bunch it up with a bunch of other writes, likely overwriting an entire stripe at once so that there is no need to read the strip first. If you copy a file in btrfs it will just create a reflink and it is a metadata-only change, etc. If you scrub your array the filesystem knows what blocks are in use and only those get checked, and if the filesystem has checksums at the block level it can do the scrub asynchronously which impacts reads less, etc. I'm sure that CPU optimizations count for something, but avoiding disk IO is going to have a much larger impact, especially with spinning disks. -- Rich

Not if it goes over the same bridge. But as they are virtual, you can make as
many as you need.

How many slots do you have for all those cards?
And don't forget there is a bandwidth limit on the PCI-bus.

Most people use a low-power machine as a server and use the fast machine as a
workstation to keep power consumption and noise down.

Really simple, there are plenty of guides around. Including how to configure it
using netifrc (which is installed by default on Gentoo)

Same goes for physical devices. Use udev-rules to name the interfaces
logically based on the MAC-address:
***
# cat 70-persistent-net.rules
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="00:16:3e:16:01:01", ATTR{dev_id}=="0x0", ATTR{type}=="1",
KERNEL=="eth*", NAME="lan"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="00:16:3e:16:01:02", ATTR{dev_id}=="0x0", ATTR{type}=="1",
KERNEL=="eth*", NAME="dmz"

A lot of it is outdated. A big cleanup would be useful there.

There is a logic to it. If you use the basic xen install, you need to do every
layer yourself.
You could also opt to go for a more ready product, like XCP, Vmware ESX,...
Those will do more for you, but also hide the interesting details to the point
of being annoying.
Bit like using Ubuntu or Redhat instead of Gentoo.

In that case, ensure your POP3-client keeps a list of message-ids (UIDL) and only downloads messages that haven't been downloaded before. Here is what the man page for fetchmail says about it: *** -U | --uidl (Keyword: uidl) Force UIDL use (effective only with POP3). Force client-side tracking of 'newness' of messages (UIDL stands for "unique ID listing" and is described in RFC1939). Use with 'keep' to use a mailbox as a baby news drop for a group of users. The fact that seen messages are skipped is logged, unless error logging is done through syslog while running in daemon mode. Note that fetchmail may automatically enable this option depending on upstream server capa- bilities. Note also that this option may be removed and forced enabled in a future fetchmail version. See also: --idfile. *** I don't know if there is an equivalent for mutt as I don't use that. -- Joost

I mean, in my case the ipv6 and tg3 is loaded automatically(maybe by udev?), not by running "modprobe ipv6". is this kind of module loading also affected by modprobe rule(in /etc/modprobe.d/*.conf)? -- Zesen Qian (钱泽森)

You may be able to use the feature of modprobe that executes a command when the module loads and that way disable the ipv6 interface. I have not tried this myself. -- Your life is like a penny.

Hello Mick, The module ipv6 has only three parameters, each of which is "disable ipv6", "disable ipv6 on all interfaces", "disable autoconf on all interfaces", none of these is what I want to achieve. Module tg3 has only on parameters which control the debug level. Currently I just call "sysctl net.ipv6.conf.enp4s0.disable_ipv6=1" in preup(), which works just fine. I 'm just wondering if there 's some more "proper" way to do it. Since in my opinion, this should be done at the first moment when the interface is present, not when the interface is up. -- Zesen Qian (钱泽森)

Unless the kernel knows of the enp4s0 interface and therefore lists it under sysctl, I can't see how it can be disabled. You could try disabling IPv6 altogether in the kernel, but this may not be what you want to achieve. Alternatively, have a look with modinfo in the module options in the unlikely chance that the module has some option which disables IPv6 functionality. -- Regards, Mick signature.asc Description: This is a digitally signed message part.
