9 I use vmware-server and also kvm for VMs.
11 Both work.
13 vmware:
15 I don't really like the web-gui, it sometimes is buggy and unreliable,
16 has ssl-issues and you need a specific firefox-plugin to access the
17 console of the VMs. It brings its own tomcat-server etc., somehow not as
18 minimalistic as we gentoo-users like things ...
20 I also don't like the need to always log into that gui as I am
21 single-user here anyway. Might be some small hack in PAM or so, never
22 researched that.
24 Aside from these issues vmware runs fine, and I like the fact that I am
25 able to connect 2 very similar USB-serial-converters to one VM,
26 something that KVM is not yet able to support AFAIK (I need them for my
27 Suunto heart-rate-monitor and GPS, both cables have the same USB-id ...).
29 This is the main reason why I haven't yet fully migrated my own VMs to ...
31 KVM:
33 It feels (and is) faster. Less overhead.
35 I really appreciate the fact that it is in the kernel, you just enable
36 it once and it is there ...
38 Very little overhead, VMs feel fast and snappy.
40 For gui I use virt-manager on top of libvirt, nice feature to have all
41 your VMs at hand in one small gnome-applet ... (it should be possible to
42 also control vmware-servers with libvirt, but this has been unreliable
43 for me).
45 I like the virtio-drivers for block- and network-devices. Fast and direct.
47 The network-setup for kvm is somewhat more complicated at first, all
48 that bridging and qtap and stuff, vmware does hide that more from you or
49 somehow makes it easier to administer (my experience ... it is very
50 likely that I don't know things ...).
52 -
54 In general both systems work fine, I use vmware out of historical
55 reasons (KVM wasn't there or as ready when I started using VMs) and KVM
56 as it seems to grow up and become a really powerful and open alternative.
58 In fact it is already ...
