Just solved it by using sda / sdb for the cdrom images instead of using hdc / hdd.

[Bug 239355] Re: KVM very, very slow with RedHat and Solaris guests
I run accross this bug on hardy, trying to install debian etch 4.0_r7 i386 as guest. The echo 'dsc_overlap:0' thing didn't help. I shutted down the machine and modified its xml file (/etc/libvirt/name-of- machine.xml) to use scsi bus instead of ide, for both cdrom and disk. After doing so, run virsh define /etc/libvirt/name-of-machine.xml and then power on the vm. Here's a snip of my xml config file that worked well. I only replace 'ide' for 'scsi' in bus attribute in target node for each disk, leaving dev as 'hd*' instead of 'sd*' (as virsh complained if I did so). devices [...] disk type='block' device='disk' source dev='/dev/raid/debian'/ target dev='hda' bus='scsi'/ /disk disk type='file' device='cdrom' source file='/path/to/debian-cd1.iso'/ target dev='hdc' bus='scsi'/ readonly/ /disk [...] /devices -- KVM very, very slow with RedHat and Solaris guests https://bugs.launchpad.net/bugs/239355 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 239355] Re: KVM very, very slow with RedHat and Solaris guests
Hi, is there any update on this topic? Will there be a fix in 8.04 for the next time? I tried echo dsc_overlap:0/proc/ide/ide1/hdc/settings but it was no use in my case, tried with both hdc and with hda. I haven't tried the kvm and virt-manager packages from TJ's PPA site yet. Can they be used for a stable production system? Will the system be updateable with these packages? BTW, using a dual cpu 64 bit machine with intel-vt.

[Bug 239355] Re: KVM very, very slow with RedHat and Solaris guests
Surely, if this is listed as fixed, nobody is going to investigate further into Hardy (long term support) which must take precedence over Intrepid. I'm getting this issue trying Gentoo minimal (hdc issue) and Debian Etch (hda issue) net install. I didn't get it with Ubuntu Hardy install under kvm. It may be that certain Kernels are most resilient to this problem when run under kvm.

[Bug 239355] Re: KVM very, very slow with RedHat and Solaris guests
I don't know how this can be considered fixed. It is certainly still a problem in Hardy. I can't really do a RHEL4 install without waiting 10+ minutes for a timeout on an alternate console so I can get in and echo a command to change the ide settings for a device. That's a pretty hefty work around for most users. There is a problem with the cdrom driver for kvm, that on hardy is not fixed.

Re: [Bug 239355] Re: KVM very, very slow with RedHat and Solaris guests
Thanks for the update Joe. I'm not asking most users to upgrade to Intrepid. I simply trying to verify that the problem is fixed in Intrepid. I, for one, cannot reproduce this issue on my Hardy machines, and I'm definitely not seeing it in Intrepid (where several advances have happened that might solve this issue). Before considering a backport of a fix to Hardy, we would like to confirm that the issue has been fixed in Intrepid. :-Dustin -- KVM very, very slow with RedHat and Solaris guests https://bugs.launchpad.net/bugs/239355 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

VT is enabled in my computer's BIOS, and the kvm modules are loaded: $ lsmod | grep kvm kvm_intel 36032 1 kvm 115252 1 kvm_intel I am able to create a new Ubuntu Hardy guest using KVM, and it works very well. If I try to create other guests based on Red Hat or Solaris, then guest runs extremely slowly and eventually hangs. I've tried a CentOS 5 guest install several times now. With each install, I've been booting the guest from a local DVD ISO file. The guest does boot the iso, but runs extremely slowly. I left a CentOS 5 guest install running for 18 hours now... during that time, I still haven't made it to anaconda. So far, I've only made it past the text based media check used by RHEL. Same with Solaris - the guest hangs right after the installer starts. I've attached a screenshot of Console 4 output inside a CentOS 5 guest during install. If I left this running overnight, the DSC: timeout messages would stack up and fill the screen. Console 1 will simply be frozen at Starting anaconda... During these very slow guest installs and hangs, guest CPU utilization is about 1%, and the host CPU utilization has been very low as well. Pleas let me know what other info I can provide.

Also notice that the command is ide1 not ide0 like my previous post.
