For the libvirt 5.8 release, I find that there is a new comment in qemu.conf: #slirp_helper = "/usr/bin/slirp-helper" It indicates that there is a slirp-helper to help setup slirp network. But I cannot find it even after I built the latest qemu(v4.1.0-1378-g98b2e3c9ab) and libvirt (v5.9.0-rc1-2-g73f91d659b). Could you please tell me where I can find that helper program? Thanks --

Hi, dears, I am processing some data with 60 columns, and 286,730 rows. Most columns are numerical value, and some columns are categorical value. It turns out that: when ntree sets to the default value (500), it says "can not allocate a vector of 1.1 GB size"; And when I set ntree to be a very small number like 10, it will run for hours. I use the (x,y) rather than the (formula,data).

Usual prologue: we're testing on CentOS 5.5, RHEL subscriptions purchased. Now trying to use virt-v2v to transfer Win2008 Server guest from ESXi host to KVM host. Have enabled SSH on ESXi host, and can connect using esx+ssh://esxhost, but procedure fails because nc isn't found on ESXi. Fair enough. BTW, ESXi looks like a radically cut down RH system (/etc/sysconfig being the give-away)?
